When players are in my PvP World, their hunger seems to regenerate for no apparent reason. They do not have a saturation effect. And from what I know, there is not an option for it. It was not happening when I first upgraded to 1.8 CraftBukkit, but I had then updated again, and it started to happen.

In my Build World, hunger regenerates (it had seemed to have been a change when I first updated to 1.8) which was good. I'm okay with that change. That world is in peaceful mode. However, my PvP World is in hard mode, and hunger is not supposed to regenerate. It seems like a visual glitch because the hunger goes down half a bar, regenerates full, goes down 1 bar, regenerates, goes down a and 1 and 1/2 bar, regenerates, and so on. I hope this makes sense
