Issue description
So I believe this has been brought up before, but evidently it has not been posted as a ticket because searching it turned up nothing, so here is the ticket. Custom ore blocks don't seem to spawn if the ores per vein value is too low.
Issue comments
Well I mean Emerald ores always spawn in veins of 1 however if you change the average ore vein size to 1 it doesn't spawn. So lets say you wanted to add Rubies to the game and make them have the same spawn mechanics as Emeralds, you literally can't get the ore to spawn. Also you can't just say it's "rare" because I set it so 40 would spawn per chunk and I used world edit to remove all stone blocks in a chunk and... nothing spawned.
The default ore gen-class is used, just configured based on the parameters given.
They are likely just much rarer in this case, I can't control how ore gen works, just settings are passed. Check the code generated around this ;)
