im NOT an expert but i see whats going on actually its because the balls keep multiplying and they lag the game more and more, causing your pc to crash!

im probably in the expert group but all i know is that once there is alot of fuzz it crashes

this doid not help.

Hello! Not an expert here but I've looked into this and right away I see one fatal flaw: Since the code uses rand.normal to calculate the mutation rate, it's possible for mutation to go negative -- this also explains why it doesn't crash every generation but rather the more fuzz you have the more likely it is to crash.

If _mutate goes too far into the negatives, the check to spawn more entities might trigger at or below 0.25m radius, causing an infinite loop. As the entities are spawned in the loop they then multiply themselves, doing the tick again, and again, and again until the end of time.

The fix for this should be really simple! -- Replace this line:
_mutate = _mutate + (rand.normal * _dnaPolution);
with this:
_mutate = math.max(0, _mutate + (rand.normal * _dnaPolution));

I really hope this helps. This worked for me so..!

But also just to confirm, it's not your computer.

Hello, also not an expert. You keep crashing because your device is a potato!

you could probably use rand.uniform01 instead of rand.normal or just math.sqrt(rand.normal ^ 2) to make it abs
