With this being one of the hottest topic on this forum,
together with another thread that is mentioning this same lag in build/buy mode [OPEN] [PC/MAC] Massive Lag when entering and exiting BuyBuild Mode, I wonder where are all the EA official Community Managers? And why they don't have a say on this matter? This silence has its own answers...
They also can reject the fact that is their game that is conflicting with vast majority of platforms, or they can say that it's currently working on the fix for this lag. Well...
Try save game after switching mods. It works for me.
