I tried to open the messages with a friend with the purple "In Lobby" status and got an Uncaught RuntimeException: Memory Access Out of Bounds. Haven't done testing to see if I can replicate because I haven't seen anyone else be marked as in lobby yet.
@Matthew0898, thanks for your bug report. I believe we have resolved this issue in the 3.2.4 release which dropped today. If it continues to happen after you have updated to the latest version, please let me know. Thanks again, and happy hanging!
