Now most of you have downloaded and installed the new 4.0.1 patch update for World of Warcraft, you may have noticed some nagging problems within the game. These “known issues” were raised in an article we posted earlier and we have an update for you to see which of them will be resolved and when along with new issues raised.
Along with the already known bugs, new ones have been found. These range from the Druid spell Insect Swarm (Balance) not being available even when your spell book tells you to visit a trainer to learn it, only to find out that the trainer says you already learnt the spell.

There has also been some confusion with the Master Riding skill, missing enhancements, authenticator issues, renamed Warlock pets, and probably a WoW players biggest nightmare — missing characters. The entire list can be found by visiting the source page below.
