804 Graphics
After a whie monsters and city improvements disappear, and no amount of scrolling out to furthest zoom and waiting for a minute fixes it. It makes it had to build cities when you can't see what you've previously built, but this is a known issue atm. Whats worse is the following image

A forest drake with a blinking cloak of invisibility!!!! (FTR, the reason my sov isn't in that image is because he ran off leaving his summons to die) If the drake leaves my line of sight when he next walks back in he'll be visible again, but only for a few turns. Again gameplay wise i wouldn't mind, but the thing did nothing other than follow my sov in a vain attempt to NOM him, even if i was on the other side of the map, if i turn spam, sure enough it'll come...then cloak...(is scared)
Other units do go invis as well after a while, but this i feel should be the poster boy:P
