Divergent model state from desktop in links-heavy models #253

I've found a couple of models that generate a divergent state with desktop when run in web over a few hundred ticks. I suspect directed links are involved, as both models use them heavily, but I haven't been able to confirm that or get to a root cause.

Fish Tank Genetic Drift is a library model, but the other SIR_ABM is attached here. Running them with the below commands will generate the divergence:

I confirmed the divergence between NetLogo Web v2.11.3 (May 2024) and NetLogo 6.4.
