I see what happened now! It looks like I typed the command "resetkeys" at some point; which resulted in losing all the keys. So, the current keys on the server are the bosses which players killed on the server themselves.

The Hive appears to be messing up the logic, I have a feeling that is why the server always triggers the Eikthyr army event even though it shouldn't.

I don't know how to explain how my main got the harder events but maybe that happened before the server's keys were reset... it did happen a while ago.
