1) Encounter type error with PID:
Whilst I dont understand what the error would mean, this applies to several events from Gen 3/4 and as such, including pokes obtained from the Pokewalker.
2)
When 'transferring' a pk4 file to pk7, the PIC changes from 0000000C to 8000000C. Is this intentional? Something certainly seems wrong here.
3)
Loading up an egg in pkhex, at least in generation 4, will set all 'NULL' values to eggs as actual values (eg met time to basically 0). As such, if you then hatch this egg in your game it will keep this and this should not happen. As such, they should remain blank and untouched.
4)
Probably intentional, but 'Encounter Type PID mismatch' applies to all Cute Charm glitch caught pokemon, and several non shinies found through this method with extremely low PIDs. Presumbly, because this is a glitch, this is intentional behaviour for PkHEX.
5)
Pokemon transferred from Generation 3 with 'Artist' ribbon obtained through contest related stuff marks as invalid.
6)
Minor: Focus is lost when trying to select text on the pkmdb Advanced Filter and hovering over the pokemon listed.
7)
Full filename for file not shown when viewing in pkmdb mode. As such difficult to work out which file is which without full field visible. More is shown by having Advanced Filter on, but still not the whole line. Should be visible.
8)
Enums in advanced searches should also be searchable by their given names which PkHex displays, e.g. Pokewalker as an encounter location for HGSS pokemon which has I think its 232 as it's enum value. This data is already displayed through the viewing screen. This already applies to the names of Pokeballs when searching for that.
