Don't know if it's known bug, I have 9 layouts and 13 event sheets. When I change the order of the event sheets, save, quit and open again, all sheets are mixed, they don't keep their position in the project bar. Layouts are ok, they stay the same. It's annoying, because I have sheets like "Level 1", "Level 2" and so on and when I click last one "Level 7" after while I realize I'm actually editing sheet "Level 5" or whatever. It's relatively ok for now, but I want to add 13 more levels and probably couple more event sheets.
