Okay so I have no idea what's going on, but here's what happened. First I bought a slave from a Medieval caravan, but then she completely disappeared later. She didn't die or run away because even when I loaded a save from directly after the trade she still wasn't there. And then, when another caravan arrived I can't interact with it all. I send my pawns to interact with them, but they just walk up to the trader and just stand there. No menu or anything.

I have a lot mods installed, but everything worked fine until now. Is my save just corrupted now?
