The current Steam version is perfect, the black screen on loading can be solved by using the proper settings (no multicore and medium or lower video memory). The spawning doesn't break the game, but it makes it unenjoyable for me. I'll wait for the next version. I have 9 hours of game time on Steam, and I think the game only crashed once or twice, and I only lost 1-2 minutes of gameplay time, though some of the loot was rerandomized as I noticed, so I lost some sweet stuff that I just found before the crash. But my saves didn't get corrupted, so I guess it's fine. The only bugs I have found were resolved around climbing through windows and fences, and I think I have once exited a house through the northern wall of the second floor (yes, wall, not a window), and ended up on the ground level. Didn't even take falling damage.
