Hello there,
first of all: thanks for the great mod, I really like it and use it in several of my runs.
I ran into an issue when using Companion Drones for 2.0 together with Factorissimo3 (factories inside factories).

Setup
Factorio version: 2.0.72
Companion Drones version: 3.1.2
Factorissimo3 version: 3.11.1
Singleplayer / Multiplayer: singleplayer

Steps to reproduce
Place a Factorissimo factory building on Nauvis and enter it (level 1).
The companion drone correctly teleports with the player into that factory surface.
Inside that factory, place another factory building (level 2) and enter it.
The player is teleported to the inner factory surface, but the companion drone is not.

Observed behavior
Instead of teleporting with the player, the drone stays on the previous surface and then flies all the way from one factory to the other.
This is especially noticeable because Factorissimo’s factories live on separate surfaces/planes, so the drone needs quite some time to catch up.

Expected behavior
The companion drone should teleport together with the player on every nested factory level, just like it does when entering the first factory.

Question
Do you think it would be possible to also teleport the drone when moving into deeper Factorissimo levels (factories inside factories)?
