If you select map view, and change the current surface
it tried to move companions on this surface! (Note: that player is just browsing the map, not moving to that surface with a physical body - I don't think companions should move between surfaces in that case)

...and then it crashes:

The mod Companion Drones 2.0 (2.0.5) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event companion-drones::on_tick (ID 0)
LuaEntity belongs to surface nauvis (index 1) but a LuaEntity belonging to surface reserve_base_surface (index 3) was expected.
stack traceback:

P.S. switched to the surface without the land and water — all are "out of the map" tiles (the special surface from some mod)

The fix for this issue is described in the other thread (needs range cap). I'm available on discord to help you or the mod author implement these changes.

In version 2.0.6 is diasbled to asign work to Companions when using Remote view - so it may solve this issue
