Map keeps crashing. Any help appreciated.

[IronForge]

I suspect its something to do with the hero revive triggers. Someone gave me this trigger code, I dont know what it does. My own leaked even worse. This now crashes 20% of the time. I don't know why. Please look over it and tell me whats wrong. Thank you!! I spent 2 days one night without sleep making this... (seriously, was my first completed map attempt even though it used an old template) and so sad to see this happen
