Hi,
well short answer is I play without the following mods: PetAI, Feverstone´s Horses, Carry On.
I tested the following with a negative result:
Deactivating PrimitiveSurvival (PS) and activating the above mentioned three, or any combination of these mods resulted in the problem.
So while the mods PetAI, Feverstone´s Horses, Carry On on their own seem to work fine, the root seems to be in another mod, or a combination. But its really hard to figure it out.
I mean technically some mods (like expanding the stacksize of items) should not have anything to do with this problem bc they dont affect damage in any way. But i cant tell that for sure which is why i asked for log files or anything like that.
cheers
