@Fosters Discovered something interesting.
When someone buys something from the Members Shop 4.5, nothing gets updated in the postbit.
However, if we manually give the medals/trophies through the AdminCP, that award medal finally shows up (and the toggle hide/unhide) works INCLUDING showing all other medals not showing previously in the postbit. That change is simultaneous for everyone regardless of groups.
The problem is inconsistent as it pops momentarily for some members (even under the same group) on random occasions.
Compatibility issue?

I'm scratching my head on this one.
