Same idea came to me

DLing atm clean SVN install in new folder. Ill write once it finishes and i try it out.
[edit] works fine now, no crashing out cause of scrolling so far. I had several memory allocation errors but after i reduced graphics from high to medium it seems to be gone.
have another bug - at one moment my resources became showing as i have 0 ... Great Farmer stopped planting Rice i been importing from Wang Gon, and standing there unable to plant anything at all... but i am able to build Taj Mahal, meaning i have Marble. Also i can build cultures which require resources in vicinity. In resources diplomacy window it looks like i have 0 of each resource for trade.
Weirdness ...
i have savegame right before it happens if it would help.
[edit 3] after 3-4 turns resources came back, but i also noticed that some of AI dont have resources showing in resources diplomacy tab as well. And after few more turns resources were gone again ...
[edit 4] Here's savegame where i don't have resources.
