This has been cleared up. This is caused by the optimization in #475 when using the inverted loop.

Update: I get a validation error of 0.0 between single and multithreaded simulations on both an x86 Threadripper 3990X and an ARM Apple M2 Pro with #581.

So I guess the bug Heisenbug somehow disappeared? Closing this for now and hoping that it won't come back...
