The latest patch for the new Bridges & Ports DLC for Cities: Skylines II changes quite some stuff under the hood. This requires many mods to be updated to be compatible with the new version, even though no major changes in the Mods' code should be required.
If you're a modder yourself, most mods should work fine after recompiling again after the update, so if your mod is included in a list as "broken", it could be as simple as that.
This thread should help you get a quick overview of what you can expect, how you can help yourself, and the current state of the mods for Cities: Skylines II after the Bridges & Ports release.

Dealing with broken mods
The community has done the heavy lifting!
Is your game still broken?
Do you play without custom content?
If you play without any custom mods, you are good to go at the time of release! (Assets like the Official Region Packs are not affected.)
Do you play with custom content?
If you do use mods, you might encounter issues if you try to launch the game at the time of release. This is because some mods you rely on may need to be updated, and might not work as intended immediately at release. Some mods might also cause your game/specific save to not work without a mod that might be broken, and it will be altered/glitched/unbootable.
Everyone receives the new patch.
Because new features and code changes are introduced into the base game, mod creators may have to implement their code in a new or different way for their mods to function again.
Mods shown as "Compatible" by Paradox Mods don’t necessarily work in the new patch immediately. This is due to many modders marking their mod to be compatible with all 1.3.* versions - with Bridges & Ports being 1.3.6f1, this means it might automatically show as compatible, without the modder actually having updated the mod yet.
Many mod creators have been given early access and have been able to work on their mods ahead of time, but these might not update immediately when the Bridges & Ports patch is released.
Please be patient. Everyone, even Cities: Skylines II mod creators, has a personal life and might be unable to update a game mod immediately at launch. Do not bug creators to update their mod.
Something that could happen if you try to play before all your mods are updated is that you can accidentally overwrite the city you're working on, so it's always good to back up your save files.
The easiest way to do this is to load into your game before the release on the 29th of October at 18:00 CEST, and create a manual save file (from the escape menu in-game) and name it something different; this means it won't be overwritten by autosave, which can potentially lock any harmful effects permanently into your save file.
You can also make a backup of your most recent save file by copying it to your desktop. Once your required mods have been patched, copy this file back to the previous folder, and you should be able to load it safely. The save file location is as follows:
C:\\Users\\%username%\\AppData\\LocalLow\\Colossal Order\\Cities Skylines IIThe creators of many of the most popular mods on Paradox Mods have had Early Access to the update and have prepared patches for their mods for this release. If you are already subscribed to these mods, you will receive the updates automatically once their creators publish the patches to Paradox Mods (unless you have specifically chosen not to use the latest mod version).
In the days after the release, modders often release multiple patches as they address unexpected behavior, so you might see a large increase in updates on Paradox Mods.
Remember, mod creators have real-world commitments that may mean they can't immediately publish updates to the Paradox Mods, even if they have confirmed to us that they have an updated version ready to go. Please have patience, and don’t go out of your way to pester, complain, or harass these mod creators while they work towards updating their mods.
TLDR;
If you use a mod that you know to be broken, DISABLE IT or REMOVE IT FROM YOUR PLAYSET.
No sense in using mods that you know are not up-to-date.
You can use the third-party software Skyve to check the status of your mods.
Skyve is a great tool if your mod collection is starting to grow quite big, and can help you identify issues with outdated and/or incompatible mods you're currently subscribed to.
Respect modders' personal lives and give them time to update their mods.
They’re all human and work on these mods out of love for the game and the community, so be nice to them with this large update.
Many community volunteers have made the gargantuan effort of compiling a list of popular mods and their status after the patch. Please note that this list is not a complete list of all mods that are on Paradox Mods, but a collection of the most popular ones.
You can find the sheet thatkjmcihas created with the help of many other community modders and testers here:
If you have a mod that you know is broken, REMOVE IT FROM YOUR PLAYSET.
Nothing good can come from knowingly playing with mods that you know are broken, and if you want to play the game before a specific mod updates, you will experience glitches, big or small.
Check this forum post for solutions to many common issues.
We have shared a list of the most common issues so that you can help us by helping yourself in diagnosing and solving common issues. Give this a look over to see if you can recognize your issue here before moving on to #3.
Report bugs in the Bug Reports forum.
If you have ruled out mods as the cause of your game acting weird, please head over to our bug reporting board on our forum to get help from Paradox directly. Filling in a form with all the information about your game really helps us diagnose game bugs. Any bug related to the usage of mods needs to be reported on the mod itself and addressed by the modder themselves.
Go to our Discord’s #cs2-tech-support channel and follow the steps there.
Our official Discord server has many good resources that could help you fix your game, and the members on there are usually happy to help you try to fix your game. Just one quick reminder: our dear moderators and tech-support are volunteers, so please thank them for their help. During large updates like this, there’s usually a large influx of people needing help, so please be patient and allow them time to answer.
Want to turn your mods off until they’re updated?
If you want to play the Vanilla game while you wait for mods to be patched but don't want to remove your mods, you can create an empty playset or temporarily add --disableModding to the game's launch options to disable all mods.
