Odd Bug I've encountered dealing with HPs

[Furinex]

So, I was playing my druid on my server, and I have a few macros that load me with buffs... So I clicked em all, (Pretty much the best buffs this build can handle) and my Max HP was 6364 but no matter how much I healed myself, my current HP would not go over 3770. I even did the #heal command. So no matter what I would do, my current HP would max out at 59%. Im not really sure if this is fixable, I checked the rules table and I couldnt find any settings for this. Also searched the forums with little luck. Anyone ever encounter this?
