Description: Silked ores seem to produce double the expected yield Server: Carrot - did not try it on Potato Expected behavior: Silked ores would be received on a 1:1 ratio Steps to reproduce: Find an ore, use a Silk Touch pickaxe and mine the ore. You'll find two ores in your inventory, rather than just one. You can then place the ore and use a Fortune Pickaxe to break it and maximize your result (redstone, lapis lazuli, diamond, etc.) How long ago was the bug introduced?: Just noticed it today Additional comments or concerns: The dupe of the ore only happens once. If you silk it and then place it and try to silk it again, you only get the expected 1:1 drop the second time.
This is intentional. MCMMO mining level gives a chance to drop double the yield when mining something (not counting fortune). When you mine an iron ore with level 1000 there is a 100% chance to get 2 iron ore. Same with any ore if you have silktouch. There's no bug here.
