In my mission, "Sleeper Agent", I had a number of NPC Groups put on the 'Lie Flat - Front' emote, so that they would appear to be sleeping. This worked beautifully when previewing my mission in the Editor. However, when I published the mission, the emote didn't occur at all. I couldn't find a work-around, so I had to delete the NPCs and just refer to 'people asleep on the ship'. So disappointed that didn't work!
