When you go through the effort and expense of upgrading to Osmium products and use either Osmium Hay or Fertilizer and have the perk for Upgrades checked, you should really never get anything under Silver as I understand it but that is not what occurs. Especially with undersea produce and animals. I can also go through a ban of 6 goats and never get an Osmium product. It is very disappointing to have it happen and makes you wonder why you went through all that effort. Another factor that should control the animals is the heart level and it the proper equipment ( temp machines ect) are in the barns. My animals are all at 10 stars and all have all the machines in the barns and I still get the above results. I really hope what ever controls this is fixed in the next update to the game.
