Orange blueprints I get as a reward from played levels often dissappear. This has happend to me many times atleast dozen. Received orange blueprints that I can see in rewards after played reward never appear in the inventory nor I can't use them to do research to upgrade weapons. This is really frustrating because now I can't upgrade the weapons I want to. And the orange blueprints are really rare and on top of that most of them dissappear.
