So since only lvl 6 seems off, it's someone's omission, and it's most probably mineAll other levels are either be spot on or within the brackets.
I think mods and/or admins can dole out the double-digit XP.Is it my imagination or are there people capable of awarding more than 5XP/award?
Report: I just hit Bugbear bang on 75xp. I watched it tick over!
