When players hit the required mcmmo level for a rankup, a few players do not get promoted. The common theme seems to be they log out right as they get the mcmmo level that causes the rankup. Then, they level up past the required level and never get promoted.

For example, a Gardener gets promoted to Farmer along the "herbalist" track when their mcmmo herbalism level reaches 20. If a player hits 20, they log out, then get back on later and go to 21 or 22 or 23, they never get promoted.

/ar fcheck does not force a promotion and appears broken.

I didn't realize that it had player data. When creating a new map and folks are starting over you have to remove the old data.
