Bug with skills / Crash / Multiplayer only

[Niko]

Me, my girl and a friend are trying to play together and have added a few mods. There have been no issues with anything till yesterday where skills started showing wrong icons and some didn't even appear.

A skillbook also teaches you a completly different skill than it should as well as some things even crashing you

When creating a new game, everyone but the host is having issues.

When going to a class, it sometimes shows pyrokinetic or warfare skills for a necromancer as well as for a fighter you some times get geomancer skills showing, this is only in character creation as well.

Anyone have any ideas what is wrong? ((We are currently trying to fix this issue and will post if it is fixed.))
