Crash with Berserk + AI value overflow

2 issues in 1 go

Save game + video

In this save game, if you cast Berserk on Gargoyles and either of the mages nearby, it leads to a crash at 004B2CF8 on Gargoyles' turn.
To my understanding, this is a process of determining the destination of the current stack depending on whether an ally can shoot (trying to protect it by moving to the adjacent hex). If my guess is correct, this whole process isn't applicable for Berserked units, as they are bound to attack any stack nearby.

It should be skipped to avoid the crash.

In the same save game, if you end your turn, the game would freeze due to AI value overflow - it can be resolved if you remove all the troops on AI.

This has always been a problem since ERA updated the max quantity of a creature stack from int 16 to int 32. Many old maps with already max-out troops + difficulty mod increasing the number of creatures = boom.
