When messing around with victory stances, I found that if I equipped the Lv30 Vet stance ‘waiting for the shot’ then previewed a different one and came back to preview ‘waiting for the shot’ again - the Lasguns appearance would swap from the default to the one I have applied on my Kantrael.
Its always been locked to the default green kantrael MGI which is why I dont like using it (It doesnt match my loadout or outfit). Testing it out in a mission and this was still the case at the end screen meaning this is a bug specific to the stance preview.
Its a bug but it proves that the stance can very easily swap the weapon to the appearance to one you have equipped, so id like to ask that this is made into a full feature instead so that the stance displays your characters actual weapon. Likewise for the other classes lvl 30 stances.
