On the realm we're playing on named "Howard family" One of my pickaxes that has silk touch and mending won't heal with xp. When I'm wielding that pickaxe I don't get any xp. The xp balls will just follow me around not being absorbed by the pick or my character. XP from workstations like furnaces just completely disappears. This may be unrelated but it also sometimes appears to be raining for me when everyone else on the realm says it is clear weather.
