Shadowknight Spear line and Bite line bugged

[Krikk]

Hello. I and some of the other SKs who play on Zeb have noticed that the Spear line of spells is bugged. Once it's mem'd, it takes about 45 seconds give or take before I can cast it, which is intended, and after i succesfuly cast it, it has about a 45 seconds refresh. However, sometimes the spell will be up, and when I try to cast it I get white text saying "Spell reuse timer not yet met" even though the spell is technically refreshed. Someone suggested that if the spell fizzles, the timer restarts, but the spell gem doesn't appear indented, as it would if it had been recently cast.
Also, the bite line of spells, which starts at level 62, seems bugged as well. It also has a reuse time of 30 - 45 seconds, and seems to have the same issue. While SKs got their spear line of spells around 2001 on live, beastlords, shamen, and rangers all got similar low-mana, 0.5 sec cast, instant damage nukes with long reuse timers. I've played a ranger through 65 on Zeb, and am confident that their line of instant nukes works perfectly. My shaman and beastlord aren't as high, but their's seems to work fine also, and I havn't heard any of those classes complain. If the spells are coded the same way, it shouldn't be too hard to find out what's wrong with the SK spear line/ Bite line.
Thank you
