now i can explain the problem. I can run and play a long time but only outside from my base. When i port or go in my base the game freeze and i have to restart it. The problem is that my base is empty and only 20x10 large. Yesterday i build it and had no problems.

I've noticed that World takes long time to load or crash sometimes too

The game is definately less stable. I hope there will be a fix for this soon. Do love the update so far! Mayhem!! haha
