What happened to the old full game runs? I see that there is now a separate leaderboard for mobile and PC, but there used to be like 5 other full game runs.

I'm interested in trying to do a set seed glitchless run. Whenever I load up the seed, -2063810908146531904, I spawn in a different place each time. Obviously this affects the run, and I think it is because of minecraft's switch in terrain generation. Do any of you know how to get it to spawn me in the same place as the previous runs? If nobody knows, would I be allowed to use a teleport command at the beginning to teleport to that spot?
