Let’s say that I build a stage for an obby. Now let’s delete some parts from that obby and hit that undo button. The parts that you deleted never come back and you can’t get them back again.
I think what’s happening is for some reason, sometimes selecting a Model in Workspace keeps it selected in explorer then when you drag and select parts from another model in workspace and delete those parts something happens. It has something to do with models not deselecting in explorer or something else.
Expected behavior
The parts or objects selected should come back if you deleted them after you hit the undo button.
What Happens: Part, Delete Part, Undo Button, Parts still gone
What Should Happen: Part, Delete Part, Undo Button, Part Comes Back
To add on to this if you are building with models in the Workspace they will not deselect from the explorer even if you click off of it. I have to select another one and click off it over and over to prevent this from happening. Multiple different models can be selected in the explorer at the same time. If you delete a part or a model while another model is still selected in the explorer and you hit the undo button the things you deleted will not come back (will not undo the deletion)
I’ve tried uninstalling and reinstalling Roblox Studio.
Happens on multiple devices
This has been bothering me for months and seems to have gotten worse these last couple weeks.
It’s gotten to the point where objects will rarely ever undo if deleted and even some properties have started failing to undo recently.
“CollisionGroup” and “Volume” for Sounds are a couple examples I encountered just yesterday.
This is a highly disruptive bug that I’ve experienced a few times now. Each time that I’ve experienced this issue, I was in team create for what that’s worth. Luckily, if you experience this issue in team create, then you can use version history to act as an undo. You might lose a bit of progress, but it’s better than losing it all depending on how much was deleted.
I’m not sure if this is a new issue or if it is related to this bug, but when deleting a model containing meshparts and re-doing it, the meshpart IDs are all empty?
Likely the reason this hasn’t been fixed yet is because it’s part of the Beta Features. You need to turn off “Input Acton System” as this is the seems to fix the issue. Make sure you restart Roblox Studio then it shouldn’t occur again.
Literally just happened again. Deleted a model, copied another model and realized that I need the old model back, tried undoing, but it seems like it didn’t register the action at all, it’s gone forever.
