Backstory: I'm about to release a big update to my underwater tileset. One of these updates involves changing the background color to black and making updrafts the ocean blue color so levels using the underwater tileset that don't use the updrafts as the water (the main gimmick), these levels can be easy differentiated from ones that do (so players can tell at a glance whether Lemmings are able to splat.)
However, in doing so, my moving backgrounds no longer appear in the level, as they will always be behind the updrafts, and thus, invisible. I'm not sure if this was intended, but I would like this to be fixed.
