So, there seems to be an issue with the chest that contains the bottle with the Spectator inside of it. The chest for the "Find the missing shipment" questline. Either that, or the fact that I earned EXP at camp by destroying it. Not sure, yet.

I took it to camp, destroyed it, and took the bottle out, completing the quest. This gave me EXP while in camp. Any saves made after this point are immediately corrupted and un-useable. Only saves from before this point will work.
