Mod Problem

So heres my issue... I started a campaign with my buddy on muli player and he doesn't use mods. I however was running something like 13 mods on my Baktrian campaign at the time. Now that I have tried to put them back on, my game will not load my Baktrian campaign. I keep getting game crashes....

Can you not disable mods and re-enable them mid campaign? Im really quite mad because I was turn 87 on my Baktrian campaign

I think it depends on the mod. I think that visual mods can be done in mid-game but anything dealing with the campaign map you cannot load a mod in the middle of a game.

Well I had the mods when I began the campaign..... all I did was turn them of in order to do a multiplayer campaign..... if I turned them back on shouldn't they work?
