Yep here it is. I would just PM it to all of you but this exploit is one Petter should probably know about.

There are no nutrients, yet 300 cells happily live here, and will do so indefinitely. They don't spread around very well--with no nutrients, swarm behavior dominates. If you place several more initial cells in an empty area, they will start a new colony.

Yeah, this really looks like another expression of the energy bug. When you set the substrate to slow motion the population declines.

I'm debating whether it makes sense to post new challenges while this bug still exists. Especially this one as it is obviously impacted.

This is a pretty extreme edge case. The maximum salinity is surely part of what makes it possible--if I turn that down a notch, they cannot survive the barren substrate. They can still max out the one with chunk size 0.25 though :-D

Regarding "slow observe", I've read elsewhere that it can reveal energy bugs like this. Are we taking it to be more accurate than regular observe or incubate? My 1-cell farter has a much shorter traveling distance in slow observe, for some reason.

So, incubate and observe are the problem/bug?

Only Petter could answer that for certain.

I tested a bit more with different settings and think I have a substrate now that doesn't allow for self sustained organisms anymore. But the bug might still support the survivability of them. Therefore I'm hesitant about this challenge now. Once Petter has fixed the bug current solutions might not be valid anymore.

I'm not able to reproduce this (no pun intended) in my latest version. Maybe I found some typo in the code earlier and fixed it but I can not remember it now. I loaded the substrate and turned on observe. They split a few times but then quickly die out. My current code is though far from release quality so it might be that i have introduced another bug that breaks this organism :P

When you fixed the energy bug that we found with Devorocytes, were Devorocytes specifically the problem, or was problem something that affected other or all cell types?

This has bug all over it. ;) :( Strictly speaking, yes, Slow Observe is more accurate. But, obviously, the more fine-grained Slow Observe results may not be free of the energy bug in question.

I've heard Slow Observe stops oscillating Neurocytes.

Yes, it can, and that would be accurate with many if not all preset settings. ;) Observe oscilates thanks to miniscule errors. :lol:
