That's weird... The only way I can think this issue would happen is if "max_sp" in player.conf was changed... Changing the max level shouldn't cause this in latest Hercules. Just reverting those level changes fixes the issue? If yes, please, give more details about what exactly you have changed.
Also, check out if there are no errors before this list of warnings, sine something else may be broken and affecting this (e.g. you broke a config file)
