Please report this error to the mod author.

Error while running event Subsurface::on_resource_depleted (ID 28)
Unknown variable: probability-coal
stack traceback:
[C]: in function 'calculate_tile_properties'
Subsurface/scripts/resources.lua:19: in function 'place_resources'
Subsurface/control.lua:233: in function 'clear_subsurface'
Subsurface/control.lua:527: in function <Subsurface/control.lua:515>

Worked on second attempt with no error.

Did you play a new savegame or an existing one?

I have this crush too, I'm trying it in map editor with a new scene

a new savegame

Receiving this error as well, with a new game as of today. 2.0.21. 3 times in a row, retrying from save after placement.
Also tried placing in a different place.
There doesn't seem to be a way around this fatal bug; please fix ASAP.

I can reproduce this error, but it only prints the error message to the chat and not crashing the game.
I'm working on it
