Thanks for the response, I forgot about it.

Yes, I understand. The problem for me with trying to make a small self contained example in that regard is that I don't think I can make it crash each time even in my full game.
Maybe I should invest a week or two, playtest and log/ diag extensively and proofread the whole game code (for invalid array/ memory stuff, ...).

Either way I'm going to monitor this and try if I can isolate the issue.
