Ctrl+Shift+R and Ctrl+Shift+S don't seem to work for me. I can rotate and scale objects manually (by clicking "edit" and then clicking "rotate" or "scale"), it's just the shortcuts that don't work. Other shortcuts function just fine. I also checked my keyboard input on a website and there doesn't seem to be any issue with my keyboard input either. This relatively small problem is literally the only reason I cannot keep working on my new beatmap and it is really infuriating, ngl. I would really appreciate some help.
