>>34265492Look up PKSM's issues page. The latest release is a fucking mess.
https://github.com/BernardoGiordano/PKSM/issues/573This is the by far the most critical issue.
It has a bug where it flags the Pokemon as traded as it should but leaves the current handler blank, which makes the Pokemon illegal.
I tested this myself by using its bank to massively transfer my Pokemon from Moon to Ultra Sun, opened the save in PKHex and they were all flagged as illegal due to a blank handler.
Also the app failed to flag any of them in the in-game Pokedex.
It's just broken as shit and yes you can get banned by using illegal Pokemon. Who knows what else it breaks in your save file.
