Invalid monster

My account bugged yesterday when the server went down.
Online progress was all reset but I kept all my monsters
Now I can’t use any but a certain few redoing online missions, if I put any super epic or above it comes up with invalid monster message

Hello Mitch,

Delete your restore code from here asap. That was to be sent as a PM to devs, not publicly displayed

Any idea wat has gone on??
