Today, we’ve changed the machines used for plays. Their CPU is better but the machines are different. It might explain some changes in the behavior of your bots. (like @RoboStac timeouts in CSB)
We’re actually migrating to Azure, and this is just a transition. So we’ll change them again for better machines soon (should be in December).
To be on the safe side, have your bot check time each turn and/or take some buffer regarding the 100ms limit.
