[Not a Bug] All mods are disabled when load a game

[bolbas]

When I start a new game with any mods and choose Standard Rules or Rise and Fall ruleset, all mods work fine. But when I load this game from autosave or save/load action, all mods are disabled.

Update: Not a Game bug. It was caused by Smooth AI Difficulty mod.

Wait. How did you find out that that mod was causing the error?
I have the same problem, I just don't have that mod.
