When I found the half built treehouse, I attached a good quality camera to the tree in the middle, activated the camera, and then left. I got back to the base to check the camera, but it didn't appear on the computer as an option. My game had an event active, and the event stayed active for about an hour. I tried everything I could think to try, including going back to the treehouse and trying to raise my reputation, but the event didn't go away. The event is Class: "arirSlapper_C" Object: "arirSlapper_C_2147465765". I had to use the scrape command to get rid of it. Every time I resume the save, the event is immediately active again and will not go away unless I scrape it. I did find the camera on the ground in front of the base again, but the event is still active.

The entities who built the tree house aren't very fond of cameras, and that is what caused the event. The ariral slapper event is probably bugged it should cause an ariral to spawn near you and chase you, sometimes entering into your base, then they will beat you up. Maybe try exploring around the base and such to see if you can get the ariral unstuck if it is stuck somewhere. although im pretty sure they just spawn in so it being stuck is pretty unlikely.
