Hello, I really like your addon but I am running in a couple of issues when trying to using it. First sometimes it crashes Blender when attempting an undo action, but most importantly, the addon seems sometimes to bug, the tile palette disappear and the sprytile widget only shows sprytile painting. This issue doesn't get resolved by rebooting Blender and I have to cumbursomely port my geometry in another Blender file. Do you know what causes this and what I should do to prevent it ? I run it on Blender 2.93.
