MMH5.5 - Heroes of Might and Magic 5.5

Under what circumstances does this happen? We have not made any changes to H5_AIProcesss.

I was playing a large map with 8 players, and after the AI took a long turn, the game started crashing during the Turquoise AI's turn, and this error message appeared. I tried saving, but each time the game crashed during the Turquoise AI's turn.
