I notice that older career mode scenarios I've completed successfully, show the green tickmark behind the title, similar to a successfully completed regular scenario. However the ones I've completed recently instead shows a diamond-like(?) symbol of various colour (silver or gold?) instead, or are just blank if I've failed them. When did this change happen? Is the green tick no longer used at all for career scenarios?
From what I can gather from my own experience, bronze silver and gold stars are awarded when you have met the point requirements for that scenario, a tick is when you've completed it but not met the bronze standard (maybe with positive point score) and blank means incomplete or negative score. Could be wrong
