When you replace text in a script using the studio script editor using the script dialog, the change does not count towards the change history of the script.
- Open a script with some content in the script editor
- Replace some text using the script editor (Ctrl+H, replace all)
- Pressing Ctrl+Z ignores the change made with the replace dialog
Additionally, this bug leads to loss of progress in team create. In team create the script change made with the replace dialog is not counted as a real change, so the changes aren’t replicated to the team create server. Thus, when you re-open the script, your changes made with the replace dialog are gone. A temporary workaround is to add and remove a space, this is still not the desired behaviour though.
I’m running ROBLOX Studio version 0.311.0.156626
