After patch 4, Shadowheart was lagging some 30 xp behind the other 3 party members.
Now, I see that in p&tch 5 Gale is also lagging. I noticed it by accident when my character and LAe'zel were ready to advance to level 3 and Shadow and Gale not.
So me and Lae'zel have 7XP in LV3
Gale has 587 XP in LV2
Shadow has 577 XP in LV2
