Not a Bug Did not receive full XP from quest

Description of the bug:
The total XP required to get from level 7 to level 8 is 560. I had a level 7 character which was close to level 8. I then did the Amoria hair quest (https://poof.ml/?p=quest&id=8860) which awards 1500 XP (after X3 quest EXP), but instead of leveling up twice as I expected, I ended up at level 8 with 839/840 XP. Even if I had 0/560 XP before doing the quest, I should still have gotten to level 9, because 560 + 840 = 1400 which is less than 1500.

In short, I did not receive full XP from the quest. It seems that there is some sort of limitation that prevents characters from leveling up more than once from a quest.



What is supposed to happen?: I was supposed to get full XP from the quest.

 

However, on my client, it said "You have gained experience (+1500)". I have edited my original post with a screenshot to illustrate this. Also, if I truly only received 1x EXP, then it would not have been possible for me to end up with 839 XP after leveling.

 

When you say level again with correct EXP, do you mean that I will be awarded the leftover EXP "owed" to me by the quest after I level up? Because I just killed a blue snail, and ended up at level 9 with 8 EXP, so it seems like the leftover EXP from that quest was not awarded.

Additional info: The blue snail gave 9 total EXP (8 base + 1 event EXP) which got me from 839/840 XP at level 8 to 8/1242 XP at level 9. Also, I logged out after finishing the quest and logged in again to kill the blue snail.
