This is because of what CA did with transports in one of the patches. They have land army movement. We have a bunch of systems in place to try to improve this, but basically without making army movement really high we can't do anything about this Its frustrating.
Thats basically an encyclopedia LOL - you want information about all units and buildings...thats what that is. We have around 2000 units and as many/more buildings, so you can imagine how long that would take. Then also we are constantly changing/fixing things with stats, etc.
