Hi , there!
I use the Yitzi's Patch...
and get sth stuck in the game...
1.
When the game is running , i click the hot key F6 and game crashed suddenly
From the crash...never use the hot key...

I remember the hot key F6 is use for illustrate our orbit satellite in original Alien Crossfire edition ...
2.
In addition , as we know , random events always start up through the game's running... such as fungal blooms by base's pollution caused , or forest expands , kelp expands ...
a while ago , i start a new customize map , in the beginning , everything is OK , (well...except the hot key F6 above...) ,
however , the campaign execute to later period (mission year : 2390-2440 ) , random events become more and more , and the game will crash with high probability at any time in the middle of events...
i really don't know how and why , so i restart another customize map again , but this time , in mission year 2439 , the crash comeout again ...

system is windows 10 64bit ,
screen Resolution is 1920*1080 ,
edit "DirectDraw=0" in Alpha Centauri.txt ,
use facedit.exe to strengthen the cyborg faction a little ,
edit "Numerator/Denominator for frequency of global warming" value to 1,512 :
0, 512 ; Numerator/Denominator for frequency of global warming (1,2 would be "half" normal warming). {0 to 32767, 1 to 32767}
and
4000 ; Normal ending year for lowest 3 difficulty levels {under -2 billion to over 2 billion}
i try to replace the game edition to the GOG , install the patch , and the same crash still happening in {mission year : 2390-2440} approximate
...
Anyway , thx for your time.
