Not really much information to give here. If I have an Excavation Pit and try to upgrade it to a Ceramics Kiln, it builds a Glassblower instead. I have manual upgrades on, so I'm selecting it from the menu. Sometimes if I try to select it (I've reloaded and retried multiple times) it just doesn't upgrade at all, and the marker telling me it's ready to upgrade stays. I tried manually reinstalling the Three in One mod in case it was a file corruption thing, but the bug remains. Anything else I can try to fix it?
