Single player on large maps.

I can not get this game to play without saves becoming unloadable or auto saves not loading.  A am testing out long gameplay modes 650 turns plus but no luck getting there.  Has anyone managed this so far?

I have a lot of crashes just in general playing on huge maps.  When somebody wins a victory the game warns that it will be unstable did you turn off victory conditions or something?

Yes only have supremacy,   But cant get past turn 200 before problems with saves.  Last game played well up to turn 137 then saved only to find all autosaves not loading.  

I love long games on huge maps I will do the same thing and turn off everything but supremacy and see how far I can go before I have problems.

I don't think I've ever made it past turn 150 without some bug or another killing the game. Or the save just decided not to load anymore.

Very frustrating for players wanting long games.  I managed 450 turns when it was update 1 but since other updates no game past 200.  This has to be fixed before game release.
