Hi, this weird one started happening to me ~4 weeks ago in a Studio update. I like to drag the Color3 picker around to find the perfect color when building. If I changed my mind, an undo would send me to the previous color I had selected.
Now it’s counting everywhere I dragged as if I saved each and every one. This makes undoing a nightmare and I’m often losing work because you can only undo so far. It is turning 1 undo into hundreds. Here’s a video:
I’m on macOS. It’s happened on both Maverick and Big Sur the same.
