Game Being Ruined

Hi all,

Looking for some help here - not sure if this is a common problem.

Have started a network game with some friends and we have all experienced during our matches - at random times - the Tactics button disappears and we are no longer in control of the team. Can't make substitutions, can't give a team talk, can't shout instructions. This KEEPS happening and is ruining the game as the assistant manager often makes bizarre substitutions in our absence! How can this be fixed? It's completely ruining the game.

Thanks in advance for help.

Is this network game timed? and or other settings maybe conflicting on the person whom creates the save?

Its been a while since i did network game so not sure.
