game crashes when in loading distance of the Castle. mods on/off with all characters

[SkullField]

i had a character i was playing when after putting quite a bit of time in to it, it started to crash after the loading screen. the only save i could load with the character was before i took the castle. this character had lots of mods that were all working for days. then i changed rich merchants to rich merchants less caps and went and ate dinner. then i couldnt load the character. i eventually turned of all mods to find the trouble maker. no luck. after lots of frustration trying to make it work i moved on to a new character. i have all these mods on, the same as the old character. everything was smooth until it was time to retake the castle. the new character crashed in loading distance of the castle. all saves in or in loading distance on any character crashes. with and without mods which means something was saved permanently. im thinking its a cell issue. how do i go about resetting the cell or something. any ideas?
here is a list of mods i use. they all work fine, but im suspecting spring cleaning or something. i do back up all my saves.
