When one of my sailors would level up the total stats displayed under the Ship Info window would increase to show the change but then next session they would go down.

Leaving me perplexed while trying to find out why; looking at my buffs and gear.

What happens is the total value of the new stats are added instead of only the increases.

My sailor four main stats went from (1.0>1.1), (1.1>1.2), (3.3>3.6), (3.5>3.7); instead of increasing the new totals with 0.1 0.1 0.3 and 0.2, 1.1 1.2 3.6 and 3.7 were added instead.

Restarting game fixes it.  It's not the first time I notice these fluctuations.

ALSO eating seafood cron meal (extra 25 mastery), while helming the ship, would update the bonus of mastery in parenthesis but not the total value (lol).
