The first few times I seen this since HoT launch I just figured I wasn’t at the event long enough, but today at the Shadow Behemoth I was there for the duration of the event, I did the pre’s and the final boss, I did get the daily reward ( as it was the daily today ) the final chest, and even the world event chest reward, but it did not give me any XP reward at all,
This has to be a bug how are you supposed to farm XP for mastery’s when world events don’t give XP rewards,
Like I said this isn’t the first time, ive also seen this at Shatterer, and Grenth in Cursed Shore.
