Wizard Instacast Bug to be Fixed

The bug that affects instacast spells, you try to cast one, and if it fails for some reason, ALL your spell gems gray out for the duration of the refresh (10 seconds), will be fixed in the next patch (February 13).

As far as I know the fix for this is done and will go out with the Patch for TBS. If it's still giving you issues let us know after that. - Nodyin, EQ Designer
