Fast Ball Aerodactyl with hidden ability is banned from Wonder Trade but marked as legal by PKHEX

[niku154]

I found that Aerodactyl with hidden ability can only be caught in gen5 dream world, so the legal ball type is either Poke ball or dream ball I guess?

I was able to duplicate the scenario, with and without hidden ability:

IIRC Aerodactyl cannot be found in the wild, so it cannot be caught Apricorn Ball.

This issue repeated with: Cranidos, Rampardos, Shieldon, Bastiodon, Archen, Archeops, Tirtuouga, Carracosta.
(the other fossils are unaffacted; they prompt the correct message Species cannot be in Apricorn Ball)


[to OP: you can use any ball when catching a Pokemon in Entree Forest, not just Dream Ball]
