My current game is quite stable, but I have one recurring crash, which happens when I fight ancestral ghosts.

Since my sign is the astronach I fight my own summoned ancestral ghosts a lot to absorb magicka, but frequently my game crashes when I do this. To be precise the game crashes, when the summoned ghosts do their attack spells. Since I crash around once per hour, I would like to avoid this.

I'm sure the problem is caused by a mod, but I don't know which, so I hope someone can tell me which. Here is my mod-list:

I don't know, but this is how Morrowind.esm defines the Summoned Ghost:

Record: CREA "ancestor_ghost_summon" Flags:0x0000 ()  NAME: ID:ancestor_ghost_summon  MODL: Model:r\AncestorGhost.NIF  FNAM: Name:Ancestor Ghost  NPDT: Type:	 (Undead)  Lev:			 1  Str:			50  Int:			50	Wil:			30  Agi:			50  Spd:			18  End:			50	Per:			50  Lck:			50  Health:		 23  Spell_Points:  400	Fatigue:	   400  Soul:		  100  Combat:		 30  Magic:		  80	Stealth:		20  Attack_Min_1:	1  Attack_Max_1:	5  Attack_Min_2:	1	Attack_Max_2:	5  Attack_Min_3:	1  Attack_Max_3:	5  Gold:			0  FLAG: 0x0448 (Walks, Skeleton_Blood)  NPCS: Spell:immune to normal weapons  NPCS: Spell:Ghost Curse  NPCS: Spell:ghost ability  NPCS: Spell:immune to disease  NPCS: Spell:immune to frost  NPCS: Spell:immune to poison  AIDT: Hello:0  Unknown_1:0  Fight:50  Flee:0  Alarm:0  Unknown_2:000000  Flags:[0xa00000 ()]  AI_W: Distance:	 1000  Duration:		5  Time_Of_Day:	 0  Unknown_1:	   0	Idle_2:		 50  Idle_3:		 50  Idle_4:		  0  Idle_5:		  0	Idle_6:		  0  Idle_7:		  0  Idle_8:		  0  Idle_9:		  0

If the problem is a mod, it seems like it could only be one of three things: They have changed this definition, or they have changed the model (r/AncestorGhost.NIF) or they have changed the spell "Ghost Curse", so maybe it uses a bugged magic effect or something.

It's easy to check for changed models, look in Meshes/r for any new AncestorGhost.nif and remove it, this will revert to the one from Morrowind.bsa.

If you aren't averse to using command line tools, http://code.google.com/p/mlox/wiki/Tes3cmd can find which mod changes things, for instance, finding which mods change the summoned ghost:

tes3cmd dump --type crea --id ghost_summon *.esm *.esp

and finding what plugins change the ghost's spell:

tes3cmd dump --type spel --id "ghost curse" *.esm *.esp

and see if the spell effect is changed.

But, my guess is that it is not a mod, and it is just the Morrowind engine being flaky.
