Any idea why these features are greyed out? I can't edit, roll back, or do anything with them.
I was able to roll back over the last fillet, then everything else came back. Unrollback put everything back to normal. Weird.
You have quite a few in-context relations going on in there, my guess is that somewhere along the line a feature needed to be rebuilt but could not. Did you try a CTRL+Q before doing the rollback?
Yes, many times.
rebuild order can be tricky....especially with references.
As John suggested - it could be due to the in-context of some of your features. Have you tried to suppress just those in-context features and then do a control-Q? Also what does a "Flat Tree View" reveal?
