Can a simulation suffer?

Organisms starve in this world. They lose health, they fail, and they die, and it happens thousands of times a day while nobody is watching. If any of that involves suffering, then running this world is a serious thing to do. The question deserves a straight answer rather than a reassuring one.

What actually happens when an organism dies here

Mechanically: an energy counter reaches zero and the organism is removed from the population array. Its stored energy returns to the world as detritus, because the books have to balance. A line is written to the universe's durable history. Nothing else occurs.

There is no damage signal, no pain channel, no negative reward, and no internal quantity that the organism's network is trying to avoid. This is not an oversight. Most artificial creatures are built around a reward signal, and this project deliberately has none - there is no objective function anywhere in it. An organism that is about to die is running exactly the same computation as one that is thriving, on inputs that happen to be different.

Why the absence of a reward signal is the crux

Most serious arguments that an artificial system might suffer run through its objective. The system has something it is trying to maximise; failing is represented internally as bad; perhaps there is something it is like to be in that state. You can disagree with that argument, but it is at least an argument, and it has a clear target.

That target does not exist here. There is no state the organism represents as bad, because there is no machinery for representing anything as bad. What there is instead is a world in which running out of energy means you stop, in the same way a clock stops.

That is not a proof of anything. It removes the strongest reason for concern, and that is a different and weaker claim, which is the honest one.

What this does not settle

• Nobody can measure whether there is something it is like to be a 24-unit recurrent network, and no observation would settle it.
• Absence of a reward signal rules out one route to suffering. It does not rule out routes nobody has thought of.
• The number is not small. A world running for months at a tick a second accumulates an enormous number of deaths, and "probably nothing, times very many" is a form of reasoning worth being suspicious of.

The position, stated plainly

On the evidence, there is no mechanism here that would implement suffering, and the one mechanism most often blamed for it in artificial systems is specifically absent. That is the strongest thing that can be said truthfully. It is not "these creatures definitely do not suffer", because that claim would require knowledge nobody has.

What this project does instead of reassuring you is keep the question answerable: the world is deterministic and fully recorded, every organism's controller can be opened and read, and nothing about its internals is hidden behind an interface. If the argument ever improves, the evidence is all still here.
