I made a DS9 set on tribble and they worked fine. But the ONLY mission objective is interacting with a crate. you don't do anything else at all. Also that's the entire mission, it has a description for the Foundry database, a grant mission dialogue, and a single objective to interact with a crate. It works fine.

I've never tried making a mission where you leave custom maps then do something in a social zone. But one of the guys in the previous foundry challenge did that and it had weird glitches.....
