I had 8800 xp total for a level 4 character. I completed the Andrews Basement quest and the combat log stated I got 183 xp. When I looked at my character sheet it had actually given me 263 xp instead, with a total of 9063 xp.

Anyone else experience this?

No, but I'd like to ;)

Sometimes it takes awhile to the game engine to update your xp from the quest itself. Its not always spot on as soon as you look.

I have this happen all the time with everything, its not that you gained to much- its a delay in the calculations. I've found this often happens in quests with lag. Normally by the end XP of the quest it sets it all up.

This might have something to do with the number of times your xp updates, and if you kill 150 gobo's, then its not likely to have added the xp and change the number image for each one, instead it makes a running rally to apply after a set amount of time.

I don't know for certain, but I can say this happens on every server, and has been for the past 5 years.

My XP ONLY updates when I open the charsheet, no more, no less, so yes, I guess the XP for the kills was not yet added.
