Remake World Bug

When I try to remake a world, weird things happens.

What I expected to happen was:
When I logged to the world, it would spawn me exactly where I logged off to remake the world.

What actually happened was:
I spawned in a completely different and random place. Bad for map makers.

Steps to Reproduce:
1-Make a world.
2-Type the coordinates.
3-Remake that world.
4-Type the coordinates of your remaked world.
5-Compare the values.
