my friend was stuck at maxie fight in ahc

so some time ago me and my friend were doing ahc together and we got to the maxie fight, we did defeat maxie but my friend didnt get teleported out and had to use /class and now hes been stuck at that stage for awhile, is there a way to do the fight again?

 

I had a similar issue where I completed AHC and was lootrunning in Corkus, as I went to grab the Security Overseer's chest I got teleported into the fight at random and kept being tp'd into it over and over, try going to the Security Overseer on the second floor of Corkus Castle, maybe it'll teleport you too
