Bug? Patch changes don't apply in campaign mission

This might be a bug, but just want to be sure, that I don’t misunderstood anything. I played the first mission of the Pyhrrus campaign again (difficulty level medium) and Lysimachos still builds Centurions and get iron age armor upgrades. Also no army tents are in the player base. Pretty much nothing has changed, but the patch notes say otherwise. So did I miss something or is this a bug? And if so, I guess checking the other supposedly changed missions is necessary aswell.
