So far I've tried (combined in order): using a spell ward to overwrite the existing hidden onedispelallspells on selfrecycleactor on selfvisual effects cleaning manual from Nexus (the issue here is that it's not a visual bug)changing race "safely" (via showracemenu alternative mod)changing race unsafely (via showracemenu)changing the race, saving, exiting, loading the new save, saving again, exiting again, loading again ("clean save" procedure, kinda)Even after all that a completely ruined gameplay-wise character is still getting staggered. I checked the Papyrus log (all logging options enabled) while getting staggered (game running in the background) but it had no messages. I decided to do a quicksave right as a spell hits me and I get staggered and then check it out with PDTWrapper. There were 6 active script threads: 2 from undeath, 1 from campfire, 1 from asis, 1 from skyrim-misc (hearthfires stuff) and 1 from EFFcore. I disabled all those mods (ouch) and still got staggered. I then saved in the same circumstances again and ran the save cleaner tool and used all options except the ones in "advanced", and got the same result. Then I also used the "advanced" options and that didn't help too. Also waiting 30 days for everything to reset didn't help too. I'll search for ways to trace active scripts in real time tomorrow and report what I find. I know this issue is very rare, based on what I've found so far so I'll do my best to log everything I do for future reference.
