Using Firefox 3 and I thing for firefox 2 same. when regeneration time hits 0 vp and other stuff does not increment for a while, even going in to the creature profile and back does not help

refreshing the page should sort it out, there's a difference in the clock timer in-game and on your computer, refreshing matches them up again, it also allows you to see the stats increase straight after the refresh, also if you look under the list of stats there's a little circle with a glowy thing going round it, when it hits '12' the stats will change automatically
