I sometimes misclick the Parent value of an instance when changing its name.
In the old version of studio if you did this and you clicked a different property the parent would stay the same, now the parent is set to nil and you have to click “Undo” to fix it which causes even more issues if you’re using the command line because the Undo doesn’t track that step. The only way to negate this action is by clicking the actual parent object to define it as the parent once again.
It would be a great quality of life update if we could get this behavior reverted to how it use to be.
