Hello, the crash when selecting for example Troll Shadowpriests is problem. Actually I probably know how to fix this bug becouse it occured in my map. The problem is that from some patch when selecting magic unit which has no "full documentation" it will result in crash. What I mean is the description of spells when you get your mouse above icon of magic unit, this icon right to damage type etc. If the unit has no writen spells it crash so the resolution is to fullfil this place.
