Greetings!

First of all, I searched the forums and Google, but couldn't find anything on this problem, hope you guys can help me:

It seems that somehow my character has become invincible without the usage of a cheat.

I noticed it when I wanted to test the Mod "Death Alternative" and jumped off a high cliff - no health bar appeared.

I then used the console command "player.damageactorvalue helath 50" to verify that the health bar generally works (it does), I regenerated normally, but I do not take any damage.

I don't lose stamina, too, but spells drain magicka as they should.

I enabled & disabled God Mode via console (tgm), but to no effect.

As far as I know, I have no Mod activated that would cause this. Any hints?
