[PAWA]

After beating the game in medium, I decided to get all the medals therefore I beat the game in hard mode. But I was missing 2 medals, the bronze star and silver star, so I went to mission 6 in easy mode, beat the game in easy, and then found my medal case with only one medal, the bronze star. I imagine that if I start beating the game again in hard mode with all the medals, I will lose the bronze star as I lost all the other medals. This makes it seem like impossible to have every medal in your case. Is it really impossible? or is it a bug? Please help...
