My classes were lost when I migrated my microsoft account to java

Is there any way to recover my old wynncraft classes that are under a different username? It is the same account just under a different username. The IP address should be the same. I am not sure if my old classes have been overwritten or not but I would like to merge the classes with my new classes if possible if not I would just like my old classes back.

 

if it's the same account then your classes should save?
if they're lost then I'm not sure they can be recovered

 

This shouldn't have deleted your old classes
