Teleportation onto physics objects is broken

[T-rexsuper1]

Description

Using iron's spells and spellbooks, or maybe other mods (not tested with other mods that add teleportation mechanics), causes unintended behavior. Sometimes it crashes the game, sometimes the inventory gets wiped after the restart, sometimes it just teleports to 0 0 0, in any case this is broken.

Steps to reproduce:

1. Have any physics object - a ship, an airplane, a single log with a physics assembler
2. Teleport onto it using teleportation spell
3. Have fun!

PS - ender pearls work fine but modded teleports, at least from iron's spells, do not.

I have the same issue. When I teleport to any simulated contraption, I fall through the world, and if I try to exit the world or if autosave saves my position, the world becomes corrupted.

Some other iron's spells spells also result in a similar issue, notably touch dig
