If i remember correct, the ai goes for the newest techs in designs and not for efficience. You can see that at the tech stat.

After some testing it looks like only the computer area has a never ending crash program.

After I initiated a crash program in the Computer Area, i can't crash an other area anymore and only crash this area. Other areas were ok till i crashed computer.

Uploaded a save (Bluestar - Crash Program in Research.dwg) and og now testing the areas ^^
