It doesn't seem to be working. First I've left everything untouched, bots did explode. Later I set attrition to -1 as the tip said when I started a new world, bots did explode. I've set the value to 0 and guess what? Bots still explode.

just test in se 0.6.85 , works anticipated.
can u test like this. exit running game and set -1 then start a new game.
print '/cheat' and enable cheat mod ,,if active print '/se-launch-satellite 10' and open Universe-explorer .
check it ?
or submit more detailed problem description?

So your way to test if a mod works is to try it in "cheat mode"? The chance that a bot will explode is so low that I would need to spend hours in the hope it would happen. Plus what "more detailed description"? As I said, I've set the value for Robot Attrition to -1 and they still explode. What else should I need to explain here?

no.i means u can check the real factor in Universe-explorer. with SE's change(or bug) ,factor cannot be changed sometimes.
if game has been created and then changes the Robot Attrition Factor 's value will not change the real factor.
i tested lots of situations , so far it works normally. but not sure all situations work correctly.
Previous replies show how to check the real factor . if Factor belows 1 or near to 0 , this mod works expected.
or not . u may need submit more details , and i will check and find what's wrong than this mod does not work.
thanks.

Sorry for the late reply (lack of time to play). I've checked the solution from other discussion to add new ore and then refresh the map and looks like it solved my problem.
It is a good idea to post it on the main site of the mod that: "you should set the value to -1 before you create a new game or to do "this" on already existing save".
