(For my play through I played with 3 Hard AI on my team, I also tried it with different AI configurations and teams.)
About halfway through the map or when my team and I have started to push the Nod forces back the game crashes. I am unsure why this is happening but it seems to consistently crash every time I play that coop map with AI on my team (Haven't tried it with human players).
Another issue as a result of the above described crash is that it corrupts the save file for the map, if I have previously saved just in case of a crash.
I have played this map a total of 8 times all resulting in the same mid game crash and a total of 3 map save corruptions.
*Note: On the previous version I had beaten this map with the AI team.
I also noticed that the units Nod spawns during this map that originate from the southern sector are different from the previous build which had the hover missile launcher spam. (I like this change the HML was dominating).
If there is something I am doing wrong with the map other that not playing with human players let me know.
