i used to play the game in Early Access before the Release in 2 months und there was no problem with Tribe NPCs Disappearing and now after i played the game after Release most of the NPCs have Disappeared in Singleplayer Mode for some unknown reason.
Note: I Started a new game after the Release patch 1.0
I Really wish this problem will be Fixed Very Soon!
Game mode: Singleplayer
Problem: Bug
