I have done more then 300+ weapon skill points using the Knuckles of Trials in Abyssea - Tahrongi fighting Thalassinon and the latent elemental resistance effect has not come off of the weapon (basically the weapon refuses to unlock)... is this a bug and the game isn't registering that Puppetmaster should be able to complete this quest??? I was closing skill chains with my automaton: Magic Morter -> Dragon Kick = Light (lvl 3 skill chain) for over 5 hours yesterday evening and another 2 hours this morning.

Can someone look into this please?

I play on the PC version.
