I have toggled the ignore flags on the appropriate 4 cells and their references (didn't touch the 'world' forms or anything, only CELL, REFR, NAVM). However on loading the esp in order to save the flag changes, I get:

Now, it loads up fine after I ignore the error, HOWEVER I now have an interior cell called simply "*" (without quotes) with a few trees and things listed near the top of the Tamriel worldspace cells!
Anyone know what's going on here?
