Does anyone know how to do the duplication glitch for 1.6.4? (its for the all advancements 1.0-1.6 set seed glitched run) I know how to do the duplication glitch for 1.8, but not for 1.6.

Hey! I want to start speedrunning SSG 1.8.9, but I have two questions.

1. Is Lunar Client 1.8.9 allowed?
2. What texture packs can I use?

So I and my two friends got a 1:46 in 3v3v3v3, but one team of 3 disconnected, so would it be verified if I submit it?
