So here is the question... can removing mods active in a save cause a summons effect gmst to break? If this is possible its a first for me but somethings happening as when the main esm's are all that's checked the summons works. I don't believe that I've added anything that changes summon effect 03 while it does sound like a dirty gmst reference the stuff I've been messing with I don't have any gmst's and I haven't been saving the game while loading a esp I'm modding back and forth... That's the effect title name when mouse is over it while its in the active effects list summon effect 03.
Added a bit latter: The mod in question that was removed was a simple class addon based on world of warcraft I was tinkering with, only classes where in it.
