My character has an active effect 'Reanimation', which probably originates from a reanimated corpse that somehow vanished, seemingly due to a bug (the 'Reanimation' spell is probably from Skyrim Redone).
Now I can not get rid of this effect any more. The remaining time of the 'Reanimation' effect is currently shown as 998 days.
Using the console command 'dispelallspells' works, but I don't want to use this because I have a lot of other effects, partly from mods, and I don't want to add them all manually again, and I am unsure about this command and its effects in general.
I tried to remove the 'Reanimation' spell, with player.removespell xyz, but this did not help, and the effect still lasts. I also tried to use the reanimation spell again on another corpse, but this had just the effect that I had two spells 'Reanimation' active.
Is there a way to get rid of this spell? I realized that the effect is active only because my conjuration level is constantly increasing. Unfortunately, I going back to a save game before the bug occured would loose a lot of game time.
