When building thousands of districts in a single city, some mechanics start to break down. Attached savegame is at ~6K districts

1. Mausoleum at Harlicarnassus causes negative science. This may have overflowed twice, for a while I had positive science again.

2. Buyout price on districts goes to 0

3. Districts are not displayed properly on the map. Some are just a grey field, on others you can still see the layout/roads but no buildings. I understand that this is likely a technical limitation, but I wish it could just make sure to always load the models "in view" and unload those not on screen for performance in such situations.

megacity.zip

includes:

- savegame

- Player.log

- Diagnostics

the log/diagnostics may contain entries from after the save, but they are still from the same game, but with more districts (I managed to forget to save after I filled the entire map)
