Hey, run into an error today:

The mod Train Control Signals (1.0.6) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Train_Control_Signals::on_train_changed_state (ID 24)
Train_Control_Signals/script/train_control_signals.lua:40: attempt to index local 'station' (a nil value)
stack traceback:
Train_Control_Signals/script/train_control_signals.lua:40: in function 'station_is_disabled'
Train_Control_Signals/script/train_control_signals.lua:145: in function 'handler'
core/lualib/event_handler.lua:47: in function <core/lualib/event_handler.lua:45>

Happened in a py modded game with Train Control Signals 1.0.6
Need more Info?

my first guess: There have been 2 temprary stops in the list. The other Stops are either not enabled (disbaled by Train Limit) or skipped (train already fulled, fuel station is skipped)
