The addon author is constantly adding new features. New code tends to have some bugs. But I dont have the problem you have. Its hard to take you seriouly with a name like afkatm14 and only 2 posts. Are you a troll or a griefer? Why do you come into our forum with misleading information? Im sorry if you really do have a problem but more than likely its not Jamba. Turn down the graphic quality in your slave especially turn down the view distance. disable any unessential addons on your slave that you dont realy need like Recount and Gearscore. Lastly you may have two addons fighting to do the same thing. For example Jamba sells greys. You may have another addon that sells grays too. Turn on "show lua errors" in your main menu settings to get a hint on your addon errors. Even the best written addons have errors but if you see the error count in the hundreds or thousands then you know something is wrong.
