Computer Swap: Assets & Mods Issues

[Thorntinio]

I've recently swapped computers and tried to move my files from one to another. I currently have Steam & Cities:Skylines freshly installed, and have copied over the old C:\Program Files (x86)\Steam\steamapps\workshop\content\255710 files to the new computer, as well as the game saves.

This is what I've tried:
Open a saved game that had no mods - works fine
Open a saved game that had mods, with mods enabled - doesn't work
Open a saved game that had mods, with mods disabled - doesn't work
Open a new game with mods enabled - works fine.

My no-mod games where crap, its my mod-games I really want to open! Please help me out!

Make sure you enable the mods in content manager then go to the steam engine and watch your download status. Wait for it to stop.
I bet your steam engine is verifying all content. You can see it by opening resource manager and clicking on disk, sor by total Bytes.

Try verifying your local files. Right click on the game on your library Steam page; select properties then local files. You'll see a verify option there. It's the first thing you should do whenever you have a problem.

Thank you for the replies, I've tried "Verifying the Integrity of Game Files" but it hasn't worked. (I can't find where the resource manager is @SkiRich, dont know if thats different?)

Do you have any other ideas?

When I click Enable All Custom Assets in the Savegames of the Content Manager, I get the following error:
"A Mod caused an error [ModException]
Details:
System.Reflection.ReflectionTypeLoadException: The classes in the module cannot be loaded.

I very much doubt you had to mess around copying the folder over...

Assets and mods you're subscribed to will surely be downloaded again when you open steam on the new PC, did you not try that first?

I would delete everything in the 255710 folder and restart steam, it should work.

@Streeto that doesn't help either, and I did copy over the folders as I wanted to make sure steam didnt muck anything up, which it did in the end. I have deleted all my files and let steam re-download them and it still didnt help.

SOLVED: In the end it was the Network Extensions 2 mod, I checked each mod and it said some people had issues and the solution was to unsub, delete, load game, close game, sub, download, and load game.
