I can only assume this mod is causing this. I only have two research mods, this and "Research Reinvented", but this would be the only mod that actually changes Rimworld's ResearchManager, and I tried putting this in a comment but it's too big. I don't currently have any normal research queued, I wanted to use the queue for Anomaly, queuing up basic research while I individually research the advanced ones.

My current assumption is either something wrong with the way the research manager works with 3 separate research types, normal, basic, and advanced, OR, it's conflicting with Research Reinvented, but I'd rather sacrifice this, because that mod completely overhauls research.
