I got this fixed. Just had the wrong opcode for stamina, which is what is sent to the client to tell it how hungry/thirsty it is. Since it wasn't getting updates, it was just consuming both every minute or so. Seems to be working fine with the new opcode. I will update the SVN soon, but it isn't worth it just to update 1 opcode. So, I will put it in with the next bigger fix I get done.
Here is the correct opcode for it if you want to update your patch_SoF.conf file manually yourself and test it out:
Give that a try and see if it works better for you.
