I did a upvote and then i got this message:
"You just earned 20 points and now have 1320 points in the Vote on a comment category.
New level reached! (Need for speed-boat)"
My stats just after the upvoting:
"Diving level Thanks for all the fish
Current XP 12690
XP left for next level 810"
We will try to reproduce this bug. (and fix it)
No worries on the messages, in the end only the actual point number counts.
I wish the level it showed me when I got this message was correct (Poseidon) :-D
