Hi @Jeremy_Hardman,
Thanks for bringing this query to our attention! Jose here from Zwift.
I’m sorry to hear that avatars are disappearing in the game, this usually happens for the following reasons:
- Internet Connection Issues
- Multiple Zwift Sessions Open
- Zwift Server Issues
In addition to the step that @Steve_Hammatt suggested, I also share this article with some steps that you can try.
If you need help with anything else, don’t hesitate to contact us at support@zwift.com
Have a nice day!
