1. I have frequent crash to deskop in release 72, though the last few releases have had more CTD than ever before. 2. Not easy to predict rate. Stable for many hours, then several CTD in a row. Then stable for a while, then Ill get 2-3 CTD within a few minutes. 3. Not a blocker, I am getting adequate playtime 4. When I engage in certain activities, like equip a new item (esp if it has light), jump, change scenes, gather a resource, the screen sometimes locks up completely. I can interact with the rest of my OS just fine. Then SOTA crashes after about 1 minute of the lockup. This sometimes happens many times in a row within a few minutes, though often I play for hours with no crashes. Historically, crashes have been rare for me (Ive played since 2014). 5. Play game. Equip something fancy like a glowing mug. Screen lock. Curse. Crash. 6. Ubuntu Linux 18.04, nVidia GeForce GTX 1050 Ti, intel i5 3.5 GHz, 16 GB RAM, SSD, via Steam.
