McMMO sometimes leads to extreme memory usage, currently users who use flatfile and MySQL are reporting this error. [under investigation]
Odd but consistent bug, possibly in the Leaf Blower passive. Setting the config variable "Skills.Woodcutting.Requires_Axe" to false allows anyone using a non-tool to insta-break leaf blocks (but oddly not bare hands). The ability still applies damage to these items regardless of it they're a tool or not, causing the item in hand to change (i.e. saplings change species, wool changes color, etc).
When users sometime use their skills, the variable shows up instead of "You ready your axe!". This is probably because of an error in the localization. [confirmed]
Users sometimes get to see variables rather than the skill's name [confirmed ]
Players are unable to shear leaves (Reports of being unavailable after level 100 due to Leaf Blower Skill, but also showing up below level 100)
When a user does a /whois, there sometimes is a risk that the skillnumber becomes yellow rather than green.
/myspawn is currently bugged [confirmed]
There are reports of people losing their stats once they logout.
When the admin add exp to an user, there is no immediate skillup like there was before, the user now has to gain a new point in any skill before all the exp gets incorporated in the skills.
When the sword skill was maxed out in MobArena, it would crash the server. Solution was to increase the max level for the skill in the mcmmo config.
After a skill level is increased to greater than or equal to 20, then the remaining XP may appear in negative numbers. [Confirmed]
You cannot pick up the second drop in double drops for herbalism [confirmed]
McMMO Abilities may be stuck "on" indefinitely.
When a server restarts, mobs from a spawner don't count as a mob from a spawner anymore. Instead, they're considered mobs that spawned naturally. Meaning, xp can be gained from it. [Confirmed]
When fishing and an enchanted item is obtained, sometimes the item has no tooltip as enchantments normally do, and gives no visible bonuses [uncomfirmed and requires testing]
ex. If you break 1 pumpkin and 2 will drop, because of herbalism, you can't pick the second one.
