I had nothing better to do - I checked out my player page.
So why is it that 'evolved' and 'teamwork' are greyed out? I know I have evolved many solutions - I know I have shared more solutions than many. So why are they greyed out? indeed - these greyed out ones also show a number - so again, why greyed out?
Just interested to know - and I know they cannot be tied to a previous group - unless not being in a previous group not only destroys history but prevents current achievement acknowledgement also.
I'm just interested - from a gaming point of view.
