Podbot mm might be incompatible with infinite_round.
It is compatible with
this version of CSDM.
Don't play 1:1 - in such cases the round ends when somebody dies (and for that ou are using the plugin infinite_round which adds some invisible bots). Don't use auto kill function (pb_autokill must be 0) in the case You dont want the round will be ended. It's not the bug in podbot mm but it's the problem You are trying to get working CS against the design Valve made it.
