I'm not sure if it's the same cause, but I am able to easily reproduce a crash on AI turn in both 0.89 and 0.89b, by loading the map from 0001063 and hitting End Turn: game always crashes at the end of Green Player's turn (could be due to an action of its last hero moving, or maybe even related to the next color player). See screenshot and attached dump.

Strange. After 3-4 attempts in 0.89 & 0.89b, the game crashed every time on Green player's turn last week. However when I tried again today, again 3-4 times in a row, the game never crashed (for the same map). Hopefully the crashdump will reveal something, but I'm changing reproducibility to 'sometimes' (at least until someone identifies a pattern).

This bug is present in StupidAI at line 160:

if(distToNearestNeighbour(ei.s->position, dists) < GameConstants::BFIELD_SIZE)

Actually, it causes most of AI crashes now.

The issue originally reported by deecee actually was the duplicate to 0001037 and is already fixed by Warmonger.
The bug observed by Zamolxis is 0000955 which is caused by 0001053.

I'm closing this as a duplicate, original issue has been fixed.
