Did you previously edit the save file with another program? In order to differentiate the two save types, PKHeX checks the overall savefile checksums. The offset of BW's overall offset is within the Join Avenue data, so that could be corrupted in your save file. Can't really infer anything else without seeing the save file.

As for the setting suggested relearn moves, works fine for me. It applies tackle. Try clicking the relearn moves box to do it manually, I guess.

Thanks, fixed in latest commit https://github.com/kwsch/PKHeX/commit/b749db10d898304df57ecc9f98449c0b3bb80ac0 The pkm doesn't have an egg met date, so the internals return 'null' for the value; null->string throws an exception

Thanks, was fixed in a prior commit but I've also updated the behavior so that loading it to tabs doesn't make it illegal https://github.com/kwsch/PKHeX/commit/cb80c020110066c65206c43de22c6c07f645aea7

Can you please post the pk1 file?

How do you read About PKHeX -> Shortcuts in the latest update?

Please read the other recent threads. This has already been reported and dealt with.

Only way I could think of it happening is you having Arceus in your party but not selected for the Maison attempt. Maybe it's giving it to all party members instead of all battle participants...?

There's no other way to get that specific memory, correct.

Yes, it's indirectly saying that the pkm must have the ribbon, and if you give it the ribbon, it'll say you can't have the ribbon, hence you have to change the invalid memory.

https://bulbapedia.bulbagarden.net/wiki/Battle_Maison#Restrictions Can't bring Arceus to the Maison, thus can never vs the Chatelaine and receive the ribbon.

All issues introduced in the last release have been reported by others & fixed, next release in a few days should resolve your issues The Shiny Manaphy is hacked. It has AbilityNumber=0, which should instead be 1 (must be either 1/2/4).

Thanks, fixed in latest commit https://github.com/kwsch/PKHeX/commit/83e61923f7ff61448f3230e2c4ad9beb8227008b

However... there is a wild encounter with the same level. Boooooo. PKHeX finds a best-match by checking moves & evolutions, with the assumption that all other details should be compatible with this best-match. This is the only case known where two different encounter types share all details except for the ability
