Rebuilding an HDA seems to press the buttons of the parameter interface, which causes callback scripts to run that shouldn't be running.
Steps to reproduce: Create HDA with button, put in a callback script, e.g. print("rebuilding presses buttons"), rebuild it in unreal with Session Sync and it'll print "rebuilding presses buttons"
