Experience Bug?
Need more data.
Its possible someone had attacked those freaks and they healed up. Thus denying you of actual xp. Much like the xp denial bug from Paragon Protectors who MoG.

Also, we're you running earlier with Patrol XP? Running out of that is the most likely reason your XP per mob dropped.
Or, in other terms, what colour was the "unfilled" bit of your XP bar before and after the reduction?
The wisdom of Shadowe: Ghostraptor: The Shadowe is wise ...; FFM: Shadowe is no longer wise.


There are also a few items in the market that can grant an XP boost as well. If you had been under the influence of an XP boost and it wore off, the XP would go down.
If the game spit out 20 dollar bills people would complain that they weren't sequentially numbered. If they were sequentially numbered people would complain that they weren't random enough.
Black Pebble is my new hero.
@ New Chemicals - No, I do not believe so since the exp loss happened during a private mission as well, and I moved to several zones to make sure the loss was not centered in just one zone or with just one mob. I killed freaks, coucil, family, etc all with same result.
@ Shadows - I had been running with patrol xp earlier but I used it up, then died, so I was running on debt (purple bar) for a while. Now low exp with debt is understandable. Half goes towards paying debt. However, I finished paying that off, my status bar showed 0 debt, when the drop happened. As if I was still only getting half exp per kill but it did not say I was paying off my non-exsistant debt.
- Now I normally do have xp boosters but I have run without them before and the loss of exp has never been this great. But maybe that was the bug and this one is things getting back to normal?? If a level 29 killing another level 29 really only worth 240 exp?
I have been playing for a few weeks now and hit level 29 earlier today on my main. I was fighting freakshow in brickstown getting the normal exp for enemies with yellow/orange names then went afk for a few minutes. When I came back and resumed fighting I started getting a LOT less then I should be! I was getting around 200 exp for yellow (level 30) freaks, and around 800 for Orange (level 31) freaks. I did just come out of debt when this happened but my dept is paid off and no longer shows I have debt but its almost as if im still only getting partial exp?! Any ideas? I took advice from someone in-game and went into a mission but exp was same, then logged, ran a repair on the game and logged back in but still getting the wrong exp.
