About turn 80 of a gigantic game I got a somewhat surprising black screen when I tried to run the battle viewer. My experience has been that I have to be much deeper into a big game before I start seeing this, but whatever. What I normally do is once it happens I start saving the game just before every battle so I can have the best chance to get a reproducible save. I was able to do this once in 0.82; interestingly, I could reproduce it but not every time, sometimes it worked, sometimes not, even though I was making exactly the same one move attack from the same save file. It has notihing to do with the complexity of the battlel this one was one vs one.
It's a hard one because it doesn't replicate reliably and because it takes a long session to get deep enough into the game to start seeing it (in my experience). This is the fastest one I have ever seen. I wouldn't be surprised if it took another 50-100 turns before I see it again.
Anyway, I have started a new ticket for this version and submitted the TM forced dump file and support tool.
EDIT: I suppose I should add that the problem with this is that mid to late game my experience is that the frequency of the black screen event sharply increases, to the point that the game gets hard to play. I am talking 25-30 hr or so into the game. LoL.
