This is an issue that I have not been able to reproduce. I understand why (from my code) you would be getting numbers at the bounds of 32-bit signed integers, but it just should not be possible, and I have not been able to do it. My kids (they are my play testers) and I played the game multiple times on different computers and have not been able to recreate this issue. Were you playing a built-in map or a random one?
Thanks for playing and for the feedback!
