My friend and I started a game yesterday, trired to reload and complete it today (1.1). It refused to start, just kept us in the Network tab forever. So we went to his house, and started a new game today, saved it, came back tonight to reloade and continue, and even on his computer/Lan, it still would not let us continue out game.
Very disapointed, since 1.05 let us FINALLY contiue saved games. Please Devs, check into this bug.
