Hi,
Recently, whenever I transfer my save from my 3DS to my laptop and open it with PKHeX, I get this error. At first, I thought it was Checkpoint that was messing with the save, but I tried the same method with my POkemon Y and UM saves and they both opened normally. Hell I even erased my OR save and started a new one and that one works but as soon as I restore my main save, it stops working with PKHeX.
Attached is the problematic save.
Thanks for any help !
