I am not sure what to do at this point so I am coming here for pointers. I have placed 4 tiles with a chest in the middle of the area just south of the Oasis in Exiled Lands. No defenders. The area is totally flat. It says a basecamp can’t be placed and the purge fails every time.
Purge bases are notoriously fickle. I would move it 50 yards away from any feature and try again. That has worked foR me, in the past.
If that doesn’t work,the spot that has never failed me (in singleplayer) is in C7, right towards the northeast end of the flat area - basically backed in towards the start of the red rocky area. That always seems to work for me.
very sad. same problem. too bugged. i hope they fix it.
