I was hitlisted by a level 232 (I am level 263) 9 hours ago and I go now to attack them and I cannot, it states that they are out of my XP range. This happened a few days ago after a much shorter period of time, about an hour and I was unable to attack as well. I was able to get in 10 hits within an hour then it stated they were out of my XP range. Did the rules change? I thought there was a 24 hour window in which we could attack those lower then our range.
