Buildings disappeared.

[zimeron]

I have been using Communitas AI, Interface, and Enhanced Gameplay without any trouble, along with some random other mods (R.E.D, Ethnic Units, City Limits, a couple other minor mods). Today I tried adding in the LS Civilizations Sets and now most buildings have disappeared. I can research them and they still show up in the Civilopedia, but once the tech is researched, the building does not show up in the production list as something that can be built. This is true for both mod civs and vanilla civs, but the Barracks, Caravansary and the Rice Paddy world wonder seem to be working fine. I have no idea what is going on here and have not been able to find any other thread about it, so forgive me if I missed something and I should have gone there. I have tried all the "normal" methods for trying to fix it, including deleting ModUserData and cache folders. I have narrowed down the issue to LS and Communitas EG (AI Tools and Intereface are fine), because removing one or the other removes the issue.
