Hello,
For answerd you post yes unfortunatly idone the usual procedure to see that,even after i wake up today nothing have change.it hard to not notice 5000xp if the total is /17064 xp,after i have done 10 quest around at this lvl + achievement of 100 male spide + close same achiemvement for Kretch Leader and 2 battle field wining side, i even remember pass the 33.33% in the first battlefield before get the quest reward i was around 52% xp and after get the 5000 i notice no big changement ( i'm around 57% now after doing 2 more quest)so as you can see weird.
I have think of something it have give probably give only 500 xp and it perhaps a typo error of 5000 ?
Thx for your consern bye.(and sorry if my english little off not my native language.)
