tail barrage vanish if I clamped something with my Clamptailattack

I used Clamp in combat, but after using it I couldn’t use Tail Barrage any more. It just kept disappearing, regardless of whether I logged out or changed my skills in the Home Cave.

Clamp, on the other hand, could be used continuously (the cooldowns would decrease, but then disappear completely), but it didn’t deal any damage; in fact, the raptors I’d clamped just jumped straight down.

tailbarrage should be visible and the cooldowns should be down
