I think you are referring to me. LOL.
And, yes it also happens on Lvl 80 missions. I'll post my version here.

This is my first post on this site so I apologize in advance if I unknowingly break rules.
-The story
So I was doing dungeon runs to reach level 80 using an SD hack released on this site. I don't know how I came across this bug(or not?) but this made my leveling up much faster.
-The principle
While in a room, I noticed that my EXP bar is blinking and it shows that it is already full and is about to level up but my EXP to level is just about 40%. It made me suspicious so I logged out my account, repatched and logged-in again. Checking, I noticed that it did not change so I decided to just ignore it. Then while in a pvp match, the "you have gained a level" message appeared. So after the game I checked my level but it did not change which I was actually expecting because I thought that it was just a system glitch. But the thing is, my missions came back(which I have already finished).
-Lightbulb switched on!!
That's when I saw this as an opportunity to use this bug(is it really a bug?) to boost up my level faster among other things i.e. get rewards continuously.
-It goes crazy..
Now, after just a day, I already reached Level 80. Now, we know that once you reached the max level, you'll get sweet missions with sweet rewards! Elena avatar, champ mode tickets, etc.
-The result
So now, because of this bug, I now have 4 sets of the Elena Avatar for Elesis.
-Fin~
Does this bug occur to you?
P.S.
Will post SS tomorrow. I just needed to get this out of my system but really have to sleep.
