Game Mechanics: Error: Timer not up. Attack 0 Ranged 4727

[RangerDW]

I keep getting a timer not up error on every other arrow I try to shoot. I can wait a good time after shooting the arrow and knowing full well my bow should be able to shoot again and i get this same message with a different random huge number where it says Ranged #. Not sure why it is doing this the other night was bow kiting and only saw message one out of every 5 arrows or so..now its every other shot =/
