Crashing getting frustrating. :(
You know... I love this game... mostly because I can mod it until I love this game
I typically play on a standard map, standard speed.
I have found that repeatedly I crash at some point typically entering the industrial age.
My latest crashed at turn 206. I do believe it has to do with the number of units on the map.
Sometimes I can just reload from the last autosave [which I have set to every turn because of crashes] and often continue. But eventually I get to the point where that does not work... then I may be able to back up a few autosaves [there are 10] and carry on past the point there I crashed... but sometimes that too does not work... at which point I usually abandon the game and start a new one.
But I would like to be able to finish a game. So I am going to start to investigate this a bit more. You see the last few times [while I did not record it accurately] it seemed to me that my crashes are occurring at the same place. As a software developer myself I can understand the joy and simplicity that is a reliable and reproducible error. So... here is a dump of the error:
Unhandled exception at 0x00582816 in CivilizationV.exe: 0xC0000005: Access violation reading location 0x00000024.

trying to access some value at some fixed offset from a pointer to a memory space kinda screams null pointer to me.
In fact grabbing the value at edx+24h and then immediately subtracting the value at edx+20h says to me "get the length of this array"
I have not bothered to tease out what the rest of this assembly code is doing but it looks a lot like iterating over the elements in an array and return when done.
I would dearly love to see this error no more
