I tested steam robots + robot attrition and did not see any problems. The robots explode as expected when there are too many of them. The game did not crash or have other issues.
Please add more info to the bug report within a few days or else I will close this as "working as intended"
That unlocks all tech by default, which also unlocks the robot survivability tech. So you need to have like 3,000 robots before it starts to kick in, and even then it can take a while.
