Multiplayer has been running stable until I started building a base it became unstable even when playing alone in a MP server. I thought it could be a general problem reinstalled the game also deleted my folder in the ''userdata'' folder. And placed back my old save, but still crashes while building.

I got a new scenario: No problems, started building a base and the game started crashing again. Seems that I got around 2-5 minutes playtime while intensely building a base.
