Ever since the latest studio update, hitting the Backspace key deletes your selected object in explorer while in build…
I’m pretty certain that it only did this in edit (without a player present). I may be wrong, however, even when attempting to drop a tool instance by using the backspace key, which it definitely has never done before. I literally can’t drop a tool into workspace in build without deleting the previously selected object (most commonly the tool itself - really sucks when you’re a gear scripter for the site like I am :().
I think it’s become a little too sensitive?
