About one or two minutes into the boss run, Shaolin disappeared after floating into the air, and the HP bar was gone as well. My partner said this bug happened yesterday too. He also said that GM Alan teleported and is aware of this issue.
I am definitely using the latest game files, but I don't know about my party as we've met for the first time during that boss run.
The Game Devs have confirmed that this bug only occurs if someone in the party is using outdated game files https://royals.ms/forum/threads/bug-in-shaolin.184684/
I will be closing this thread as this bug occurs only if the party member(s) are using outdated game files If the bug still occurs despite all of the involved members are using latest game files, please create a new thread with screenshots of each party members client window (including the date displayed on top left) so that we may investigate the matter
