Hi there i'm a bit new to Krita and was playing around with and working on a piece and suddenly my brushes locked up. By that I mean no matter what brush I select or even try to erase nothing happens and no changes happen to the layer. It seems to only be the one piece because when I open up a new project it works fine. Any help would be greatly appreciated!

Do you have a selection active?

Just looked at that and it helped, thank you very much!
