While playing with this mod, I noticed a Shaft Elevator object in the starting area. After dismantling it, the game throws the following critical error.

The mod DeepCore Exile (0.2.1) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event deepcore-exile::on_player_mined_entity (ID 74)
deepcore-exile/control.lua:6041: attempt to call global 'target_for_shaft' (a nil value)
stack traceback:
deepcore-exile/control.lua:6041: in function 'remove_paired_shaft'

forgeworks-core/lib/events.lua:33: in function 'dispatch'
forgeworks-core/lib/events.lua:82: in function <forgeworks-core/lib/events.lua:81>

After confirming this error, the game closes.

Additionally...
Furthermore, if you place the exact same object from the items given at the start of the game and dismantle it again, a critical error also occurs.

i got that same crash
