Title pretty much says it... in combat, health bars are at times not updating until a later turn (i.e. takes 10 damage out of 40 hp one turn. Health bar stays fully green until next turn, when takes another 10 damage. Now updates from a full bar to a half bar). While the numerical is correct, it defeats the purpose of the bar if you still have to mouse over your character to verify their health via tooltip.
Also, sometimes it seems the health bar updates as soon as you click on an enemy instead of after the attack animation completes. Much less of an issue, but possibly related.
Thanks, hope this helps.
