im having the same problem with kakuzu in the wave after i actually gave up on trying to interupt deidara though i've tried to put neji in the front line to interupt in time but it just seems impossable to interupt so far maybe its bug'd
trying to test out combo's that might work with out double interupt maybe if there is enough healing on the field we wont need 2 interupts the shadow clone fodder is a possable problem though
