Kuu: You can discuss, it's just that since the game hasn't started yet, you can't vote yet.
Rolled: In WWG1 and 2, there was no need for a discrete deadline, as everyone confirmed their roles; this is the first time it's taken this long for everyone to confirm. As this is a precedent for me, I'll give this serious consideration.
Derekku: Every Role ID distributed is important, even Civvies, as it helps keep the balance; therefore, if those two don't confirm and I decide to start anyway, I MUST redistribute any Alien or Aux Roles those players may possess to people who are currently ordinary Civilians (a policy I've actually had for a while, but never had to mention).
(If several people - enough to upset the overall approximate Human to Alien ratio - were to not reply, I would then have to do a complete scrap-and-redistribute of all Role IDs, but I don't believe that is warranted in this case.)
