Changelog Fixed cut/copy in Tile Collision Editor (#2075) Fixed crash when trying to add Wang colors without a selected Wang set (#2083) tBIN plugin: Fixed hang when locating missing tileset image (#2068) CSV plugin: Fixed exporting of grouped tile layers Many thanks to those who brought up these issues!
