This might be common knowledge but every once in a while the layout in the Nether will change slightly. Does anyone know why it happens? Maybe there is some optimization to be found? I can find pics to compare when it happens if no one knows what I'm talking about.

Are you talking about the bit travelling through the basalt deltas where there’s sometimes lava source blocks at the flat area and sometimes there aren’t?

If that’s what you mean, it shouldn’t affect the run that much.

Sometimes the world can generate differently but most of those changes don’t really affect gameplay

thats just how it is, while i ran an enter end seed i noticed the trees also werent the same so things like that can be affected too
