I'm building a long-distance signal transmission line for a railroad system. I think it will work because the player moves through chunks with the signal, but I want to test what happens to the circuit at the origin of the signal after the chunk unloads and reloads. I haven't built the real thing yet; I'm still sketching in a Creative Mode world.
I know that F3+A is supposed to reload chunks, but it's not clear to me which chunks are reloaded and to what degree.
What's the easiest way to set up a circuit, force the chunk to reload, and see what the effects are?
