There are definitely some bugs that haven't been figured out at all like this one. I've seen this exact same thing happen for maybe like 6 or 7 of the maps and each time its so random that I can never understand it. But if there's any consolation this rarely ever happens. SinBad talked about the ideas of abusing these glitches a couple years ago but with it being a small game that has pretty much been forgotten there wasn't any effort put into figuring them out.
