thanks Superku!

we do have a console but we ended up not really using it
I can pretty much pinpoint when the crash happens, though (like I said, when loading a new level). I'm just not sure what causes it to crash. Again, I think it's memory corruption but I'm not sure.

Another thing: it looks like these crashes only happen on windows 10 so far.
If it's memory-related, I still think it's something produced by the code, though. The different operating systems might handle memory allocation/management differently which makes the crashes we're having more likely on win 10.
