Instant Portraits failing to apply when linked to a gearset

[PangTong]

With further testing, it turned out this was only happening when I switched from specific gearsets. When I switched from Warrior the error occurred, but on most other jobs it was fine.

I was able to discover that the problem occurs when the status of the gearset's /showhelm and /visor is different to the gearset with the linked portrait.

For example if the gearset with the linked portrait has the helmet showing, and you switch to it from a gearset with the helmet hidden, the "inconsistent gear configuration" error occurs. Similarly if you are on a gearset with the /visor option ON and you switch to a gearset with a linked portrait that has the /visor option OFF, the error occurs. Even if the helmets on both sets are hidden, or have no visor option, the error will occur if the visor option is different between the two sets.

The weapon hide/show option has no effect, you can switch to and from a set with different settings and the error will not occur.

So I can only reason there is some bug with how the game handles setting the portrait when switching from a gearset where the helmet and visor options are different.
