Last time, you kept them until the next colo started, and then they poofed.

Alrightly thanks! I'll hold onto them for now then I guess, until the bugs with the Nest are fixed, I'm a little worried about doing them atm.

Is there any place to see updates / patch notes for the game? I saw someone post some in another thread, maybe I should go ask in that one instead xD

All we know for that is whatever gets posted in the game itself, in the news under it, or on facebook/twitter.
