Whatever happened, happened on its own. After going back a week to another version of this widget I noticed the parent class was wrong, another widget. Which happened to be the panel it was placed on as well. Now normally you would get an error that a UserWidget can not have a widget hierarchy if its parent already has one. Nothing. No error no nothing. It occasionally freaked out on a button going invalid or having a duplicate widget binding. Seems to be the cause. After fixing it it still complains about widget pointers going invalid which are clearly present in the hierarchy.
