Seen lots of hate against PKSM recently. People complaining it fucks your mons in the storage, which isn't true. From version 5.0.0 it has a new setting which disables any editing when you store stuff in your bank, so your mons will be the exact same as in your save, but just in another place.

An extreme amount of bugs has been fixed in the last release, too. https://github.com/BernardoGiordano/PKSM/releases/tag/5.0.1
