I Checked if Exp had been turned of , No it not, i checked to see if in Public Channels System was selected it was but Kill exp is not shown, the part going to research shows and Bonus % shows but not the exp any help ?
It could be that all your exp is going to research. You may want to check your percentages. If research is 100% your ratio may be such that there is nothing left after the research to fill up your experience bar.
Just a thought.
