So I was going to made some edits in edit mode to the legs of my avatar by adjusting some of the faces/verrtices, but if I remember correctly (haven't used blender in like 7 months) this fucks up my avatar's blendshapes/shapekeys unless I do something specific first before making the edits?

or something?

sorry to be vague but I barely remember this shit and I don't want to make a bunch of edits then realize I fucked up my blendshapes after and have to re-do the whole thing
