As noted in the steps to reproduce and the screenshots, I launched the mobile xat app at around 10:20am cst and noticed a user with the display name "DoodleLove" and a purple pawn. I clicked on them to notice they had no ID data (only a single 2 was displayed), and they were labeled as "Offline Help"; depite appearing high in the userlist.
Upon asking another user (using desktop xat.com) whether or not they could see the user, they said they could not see the user.
Seems unreproducible, however I figured it'd be worth filing the information (for now).
Step 1: Launched mobile xat app (iOS)

Step 4: Clicked on said user, only to find they had no ID, and were labeled "Offline"
Step 4.5: Did not appear to other users
