Known Issues: Updated August 6, 2015

Did they really change Potion Pot again? Before this patch, it worked properly in areas restricting potion usage (thus applying the 30 second cooldown), but now it doesn't heal hp/mp at all.

They really messed it up this time. It works in places with a potion cooldown if you manually click it in your inventory, or if you have it set to an Auto HP pouch (though it'll still only work if your potions are off-cooldown). It also doesn't seem to heal through deaths anymore.

Also I noticed that using a potion pot with an Auto HP pouch doesn't heal DR damage either. I was attacking Madman Ranmaru while he had DR up, and it wouldn't heal me.
