Well...

There is a mod I wrote a before the dragonborn DLC came out... I installed it after returning to play Skyrim and my game crashes more than usually. While not sure if MY mod causes the crashes I did found this on my papyrus log.

Error: Property dyReanimateAB on script dyReanimateMS attached to Active effect 2 on (000721DF) cannot be bound because (2600FB23) is not the right type

Its a script from my mod.. and I don't understand this error log at all.

Have you tried to disable that mode ????

If yes, and you have no crashes, the culprit should be that mode.

It sounds like the object has been deleted...
