The worlds transferred from consoles only for Classic/small and medium-sized worlds aren't an 8:1 (1 block in nether = 8 blocks overworld). Small is 3:1 and medium is 6:1. I played on my transferred world from the legacy consoles. I found this out when playing using nether portals to travel, it was a small distance traveled, 1000 in nether to 3000 in over. 8000 is bigger than 3000. This bug needs to be fixed for all worlds soon. Fixing traveling quickly. Make the nether scale from 3/6 to 8.
