Hey there.
I just recently sat down to learn how to USE PKHeX's Batch Editor.
I have 728 PK files to edit with it. All legal prior to editing. I'm editing in New trainer details and making sure all the files match the Ultra Moon OT data.
After editing, all the files now show Illegal until they have the legality check ran then they show as legal.
I spoke with Sabresite and he said it was some form of deferred legality check
Is there any way to avoid this check? The whole reason for me to use the batch editor is to make simple legal changes
The string I'm using
