Solved Game crashes when opening map (tab)

Well, I was just hosting a game with 8 players. We got through normal, all good. (except one guy that kept crashing..)
Then hosted an 8 player nightmare game. Once I went to Act2 after Andarial, my game crashed. Now, everytime I rejoin the game and open the map (with TAB)
the game crashes. I tried like 6 times before giving up.

Any thoughts? Maybe a new bug that came with the patch or so?
Something caused by maphack somehow?

Additional info:
Was using Sting maphack before crashes, still crashed after closing the entire program.
I didn't have the problem when joining a new game. It seems the older game is somehow corrupted (for just me, not the others)
