2. Some mods had multiple copies of different versions in my docs folder. I deleted the old versions and kept only the new ones.
Sadly it looks like wasn't clearly stated in patch notes but after latest update we changed issue with mods being renamed (some invalid characters) so some mods which were renamed could be downloaded again with correct names - and this is causing "few mods" to have same version. Sorry for that.
To solve this: clearing Mods folder is preferable - mods (ones from workshop) will be synced correctly upon starting a game.
We also noted some issue that there were a faulty mods messing with story and scripting which could lead game to run with issues. Those mods were removed from workshop eventually, but since Steam don't handle removing from file system when mod was removed or unsubscribed from those still could be inside Mods folder.
More case: we found a issue that if client has older version of mod and server has newer version - upon syncing old mods won't be updated.
List of mods you giving us very helpful, please continue! We observing few issues with our mods system and mods from workshop.
One more thing. If you have extensive list of mods used in the same time - it may be quite a big amount of data (if amount of mods is about 1 GB) to be synced with client that doesn't have them - this may take a while for peer to download them from client. Especially for 4 peers draining data from GM host.
