ROM Hack Question Pokemon Save Editing For PKHeX, Save File Corrupted

[regret123]

Pokemon Save editing via pkhex- im able to memloader/mount etc my system, get the save file, decrypt, etc etc. Open it in pkhex, make whatever changes i want, etc. However! Injecting is somehow messing up. Upon booting game, tells me the save file is corrupted. A friend is able to load in the save just fine that i create however. same files, same coding, etc as him.
inject.bat;
