Do you mod cities skylines? If so, did you mods and save files transfer over from Windows?

Both are handled through steam (cloud and workshop subscriptions) so both saves and mods were automatically synced after installation.
That being said, you have to manually enable the mods within CS, but you have to do that under windows as well after a fresh installation.
However, I‘m missing some buildings (the european looking schools), but I didn‘t bother yet to find out what happened to them.
