Reached turn 321, 341, 343, and now 351 on an Immense map with all races AI Godlike.
Same specs as my 0.70.5 bug reports. I will state that saving the game and loading it will *sometimes* cause a CTD immediately on the load, usually after it's finished running the turn que. However, sometimes the load completes fine and I was able to continue, as per my sentence up top.
Additional notes--technically it has only CTD'd once on the reload of the "wait" save. My last three loads have worked fine.
Loaded the game and then ran 'soak' just to see how long it would go before another hang, this time turn 370.
