Okay, I've dug up two artifacts for Kongo and two for Buenos Ares. I've got two archaeological museums. Artifacts are automatically slotted so I don't get to decide where they go, and a tooltip informs me I can't move them until the museum is full. This seems like a fairly onerous and unnecessarily restrictive design, but maybe there's a reason One museum is now full. I go to move a Kong artifact out of it to sit in the other museum with a Kongo artifact. Can't do it. I can drag it, but it won't go into a slot in the other museum. Can anyone explain how this is supposed to work?
