Feldon The bug that was preventing the Tradeskill Bonus XP in certain instances such as Guild Halls has been corrected. In addition, this July 4th weekend has been changed to award a +50% bonus to Combat XP, Adventure XP, and Tradeskill XP. Although EQ2Players and the forums were accurate, an e-mail that went out could have been interpreted to suggest that Combat XP was getting a bonus this weekend.
