Yes, sometimes the mod glitches. Your character might T-pose mid-emote. The “floss” animation might look like your crewmate is having a seizure. That’s fine. Lean into it. Call it a “new dance move.” Blame it on the vents. The fun is in the mess.
Also, don’t be surprised if you start emoting in real life. After a few rounds, you’ll find yourself accidentally dabbing in the grocery store. It’s a side effect. Embrace it. You’re now part of the Emote Mod cult. Welcome.
