Here's another one that really bugs me.
You have, say, a neutral plane draft. Several surfaces in the feature, you redefine one of the parents and you lose a surface out of your draft feature. You regen, get to the draft and you get the message "confirm to remove deleted references" or something like that. You confirm, your other surfaces are fine, away you go. Same thing for rounds. But when you have a shell with specific thickness surfaces, and some of those go, what do you do? It won't let you reset to default thickness, because you have to pick the surface to do that, and it isn't there any more. But it won't solve the shell and let me move on. I have about 20 features hanging off this shell, as well as child parts that reference some of the surfaces. Is there any way I can get the shell to forget about these surfaces? I should add I don't even know what they are - everything still seems to be there.
