Well, I just noticed that if you are inside the defensive quarters (loreroot), the credits do not give VE..although AP and VP seem to be added normally. Could it be that it is a sanctuary or?

Just checking.. did you have max VE at the time? If you did, you may not have gained any because the timer reset, and when that happens, any VE over the max value disappears. Sometimes, you're not aware the timer reset because it lags and you have to refresh the interface to see the correct amount of time left to reset. Another thing is that the stats, including VE, only update when the bar on the golden circle under your stats reach 12 o'clock position--so if the timer resets in that time, which is like eight seconds, you won't see the VE gain over max value before it disappears. Or it could be someone attacked you without you noticing?

Those are the explanations I can think of. If it's not any of those, it could be a bug. There's been multiple topics about it in the past month or so, although none of the players seem to say that the problem repeats so I tend to assume it was just one of the above possibilities.
