I keep getting CTD in all the games i have played since upgrading to .31.
This has usually happened fairly early and made the games unplayable. its a shame because i really like it.
Here's the save from the turn before.

Actually i just had that problem

Update your game from inside the game.
Under Advanced >> CHeck for updates.

Your BTS should be 3.13
and your CivIV should be 1.74

all i did and mine works fine now

-- sure way to check. Check your version. If you can't figure that. See if your civilopedia shows FFH entries or regular BTS entries.

i never experienced any crashes in .30 previously.
then i played .31 (patch 'e') and never experienced any crashes.
then i loaded someone else's patch 'd' .31 game and played it (without crashes)
but now everytime i play a game with either .30 or .31 it crashes after about 50-150 turns.
I already posted one save with the .31 crash but here's one with the .30 crash.

I am very desperate for a solution. any ideas?
