Great Hall and bronze vs silver medals
I'm aware that silver medals are worth 2x bronze medals in the Great Hall. I'm surmising by my experience that the two types of medals are exclusive, and can't be used together to complete one GH award; ie., I've got 124 bronze medals, and recently moved to silver gaining 24 silver medals so far.
I'm assuming that those two groups of medals cannot be glommed together for a level 2 bronze bonus. Would I be correct?
