My save file corrupted so I restarted on an old save about 50 turns back. Thing was I had an axe with the Maul ability. So I wanted it back and killed a monster spawn then proceeded to save load to keep getting new loot items in pursuit of this axe. Well in teh process if you equip the items as you get them and reload ceratain items will cause the subsequnet reload to hang the game.

Not entirely certain the specific items cause the hang but within 10 reloads the game is hung. I thought I'd post this in hopes it could help you gusy find the reason easier as it's a pretty easy and straightfoward way to make the game hang.
