It's the Pathfinder 1E by Roll20 sheet. Lately it's been hit or miss whether the sheet's auto-calculation updates the stats. I change a skill rank, for example, and the total doesn't update even if I refresh Roll20. I have to change a number to zero and then back, sometimes more than once, to get it to update. I've tried it in chrome and firefox with the same result. Clicking or tabbing to somewhere else on the sheet also doesn't help. This is a recent problem and everything was fine a couple months ago.
