Alot..
One thing that might be good to know, after the update, after I enabled all mods again. The game would not start again.. Pressed the icon, nothing happens. No crash, no message (no visible process in my taskmanager). Nothing.
So I started enabling mods 1 by 1 and found one, that if enabled, caused the game to not start.
"229th Combined Objects Mod 1.4"
