The patches are save game compatible.. so your old save's engine will be the latest if you have updated your game. If you havent then you might still on the old patch & maybe the tactic might just not work on the older versions.. he made it for the latest patch!I'm just about to start using this tactic on an old save from patch 13.1 or something. If I load it up again will it have the old 13.1 engine running or will it use 13.3 engine i.e. making this tactic as effective?
