There's a problem if i don't have optifine,
I create the world, i do the recording BUT when i save & quit it just freezes, so i'll add optifine.
This was the result for singleplayer(it seems to be fixed now? idk what to tell): https://hastebin.com/wadimepiqo
This was the result for multiplayer(new fresh start after singleplayer with new recording, again seems to be fixed but the old recording nope): https://hastebin.com/eqifefejud
