Are you sure it does not occur in classic LoD?I heard that there was a bug with double claws, where certain skills only used one claw...
(and, a very obvious bug, if you have two claws and hit with FoF, CoT or BoI, then you get two chargeups at once... unless one attack misses. TS, CS and PS do not have this problem, which may mean that they indeed only use one claw)
