getting into someones base

i knew the old method which required logging out when underneath someones base on a rock, then logging back in and you would spawn in their base, thing is, it's patched now. i tried a few times today, and just died from standing on the rock when about to log out, got any other ideas to get in?

Put animal fat on the furnace and make biofuel after use biofuel on the base and shoot an arrow with fire on it and the base will burn

Will that work for metal bases? I'm also trying to find a way to get into/glitch into a metal base.
