Not really to be honest. Mega, Tera, but I did just do some more testing and it seems that I can not add a Zcrystals to a pokemon. Like the fire one not being able to be given to my Charmander with a fire move. I hope this helps.Ok well, based on the error, the issue seems to be a move-related issue. It's basically saying that it can't find any compatible Max Move with one of (or all) the moves in the Pokemon's moveset. I don't really know how that could be though, considering there's at least one Max Move for every type, so there shouldn't be an issue where no Max Move can be found. Do you have the same issue with Z-Moves, too? Did you add any custom types or moves?
