Fixed a bug where setting mana costs to be higher than 50 or so would cause mana gains instead of losses.
Altered air to only work in water, since it didn't do anything otherwise.
Updated the version listed in plugin.yml, which I forgot to do last time.
Items dropped by food will sometimes be impossible to pick up.
Summoned wolves will sometimes mysteriously lose their target, basically giving the player an ordinary tamed wolf. The wolf WILL vanish when the target dies anyway, but if the server restarts first, there is basically no difference.
If the server restarts before an item dropped with taunt is retrieved, the person who dropped it can no longer pick it up.
