So therefore... the quest is not updating properly. Looking at the quest stage scripting, it's registered to update every 5 seconds. I checked several places for where there may be malformed PEXes (but not all... that'd take combing a lot of BSAs), I've checked in TES5Edit on a myriad of quest, NPC, package, faction, etc forms to see if there was some override shennanigans going on... and nothing. I have yet to diagnose the root cause of why it's not updating. if all else fails, I can maybe just toss in the original PEXes as loose files to overwrite any possible bad ones in BSAs.
So... is there a way to maybe give it a proverbial percussive maintenance and force the quest to update via script? I checked the script properties in question (again with SQV) and they all filled properly... it's just not running for some reason. Maybe a "script potion" can be written to force it if it can't be done via console? I've troubleshot problems before in FO3 using such a method when the console did not avail me... but I am still

I managed to kick along via console a messed up Durnehviir fight/meet script when a malformed messed up script involved with that somehow got into my setup (and removing it didn't fix it, the bad script properties were already in). I'm hoping I can fix this mess too.
