I receive the following error when trying to schedule a train to change surfaces:
The mod Subsurface - build beneath your base! (1.1.12) caused a non-recoverable error.
Please report this error to the mod author.
Error while running event Subsurface::on_tick (ID 0)
__Subsurface__/scripts/trains.lua:247: attempt to index field 'stop1' (a nil value)
stack traceback:
__Subsurface__/scripts/trains.lua:247: in function 'handle_subways'
__Subsurface__/control.lua:362: in function <__Subsurface__/control.lua:349>
When manually driving the train it changes surface fine without crashing, but when trying to schedule the train this happens
