To close the loop - I have experienced this type of rare issue (i.e. a feature doesn't properly regenerate until "redefine without modification" is used to force regeneration) before in past models, on a Wildfire build. The purpose of my posting here was simply to alert the community in case it happens to somebody else, and also to see if anybody had any prior insight into it. I suspected that perhaps there was a relation that was possibly delaying the regeneration, but did not find any in my latest look into it. The "solution" that I posted along with the problem (numbered items 4 and 5) does get the user out of a broken-model jam but does not address root cause, so while it offers a workaround and worth knowing about, it is not a true "solution" in my opinion. However it is a rare issue in my experience and not a major problem in my opinion. I prefer not to post my native CAD file to the entire community as it may contain some sensitive information, and I could not reproduce the error in a generic CAD model as I also noted in another message.
