Game Mechanics: Sneak bug?

[stormheaven]

I've been banking in cabilis on my rog from lv41 till lv50. I've noticed when you interact with the banker the hide/sneak is reusable, which makes the banker kos, but bank window is showing. Hide succeeds after interaction but Sneak is always 100% fail after the interaction with npc, so I have to wait for it to refresh after the fail mssg.

Question is this a bug?
-Interact with banker with sneak/hide on
-Bank window pops up with sneak/hide being reusable
-Hide succeeds but sneak 100% fail on the first time EVERYTIME of the interaction, have to wait for 2nd sneak pop up before moving.
