Village Railways now runs on Paper 1.20.1. It's the same 1.0.2 as on the newer versions, with a few blocks swapped for ones 1.20.1 has.

• 1.20.1 has no copper lanterns, copper chains, copper trapdoors or cushions, so lines and stations use plain lanterns and chains, the large station gets iron trapdoors, and its benches go without cushions.
• When lines are built into land that is already loaded, which happens after /villagerailways openland, a block they remove still reacts the way it would if a player broke it, so a chest in the way drops what is in it. Paper 1.20.1 gives a plugin no way to stop that. Land that generates after the plugin is installed is not affected.
