Rich Mithril Vein only gives 1-3 hits
I have noticed that myself on some of the rich nodes in Silverwastes too, just 3 hits instead of ten.
and those 3 hits only give you 2 mithril ore. Also, in that zone in particular if you mine all of the ore there once, it’s gone until reset. It doesn’t respawn. I can chop trees and harvest cactus all day and they respawn as they should. Mithril doesn’t.
I thought this was kind of intended. It happens when you do different instances of the map several times after mineing the rich nodes. So if you mine a rich vein once and then try to mine the same one in another shard it won’t work as a rich vein.
But I didn’t do that. Mined just once. It happened on the first instance.
