Say I have collected a couple of samples, thus locking up 2 of my dice. When it is my turn to roll can I decide to 'dump' the two samples back into the treatment center and reclaim the two dice that where locked up? Thus rolling all my dice.
For eg I have 2 blue samples, another player has collected 4 blue samples and it seems unlikely I can get my 2 samples over to him without wasting turns, Can I dump the 2 blue ones and get my dice back? Leaving the 2 blue treated dice for the other player to sample later?
Alternatively, I have 2 blue samples and there are no more blue infections out, It would be handy to just dump these 2 back into the treatment center so I can roll the 2 dice during my roll.
My only concern is this could be 'gamed' a little by just sampling as much as I can if I have fears of an impending epidemic and then dumping them all back in after the epidemic has happened.
