The game is crashing after random time, generally between 10mn-15mn, sometimes less.
I'm experiencing this behavior on both stable and experimental versions (Steam was set to experimental in 0.49, I downgraded to 0.48).
Files integrity has been checked successfully.
No specific pattern to reproduce the issue, just playing a few moments.
Most often (approx 75%) I experienced a big lag 5s-10s before the crash, and 1s-2s before the crash I can see the building textures disapearing.
