My mod list wont load even though they are all updated to 1.1

[benedikth]

So I made my mod list and for some reason they wont load. When I restart to load them none of them will actually and when I go to the mod tab in game they all disappear/reset (using mod manager). The mod manager appears to be loaded but only core and royalty are on the loaded mods side. Any help is appreciated.

When the mod list get reseted by Rimworld itself, some critical error happen during the mod initialize after the activaton.
You should try to activate them all at once, do it at small batches.
Then you will notice which is the bad mod.
And btw. check the log window after each activation batch, when any error appear, you should avoid these mods too.
