Game Version: 0.17.63 build 46739
mod version: 0.17.22
When loading the save, the following error message appears:

Electric Train mod caused a fatal error.
Please report this error to the author of the mod.

Error while running event ElectricTrain :: on_nth_tick (2)
ElectricTrain / control.lua: 179: attempt to index field 'burner' (a nil value)
stack traceback:
ElectricTrain / control.lua: 179: in function < ElectricTrain / control.lua: 172>

I have tested it with 0.17.62 and 0.17.64 and could not adjust this error. Did you install other mods?

double-checked, it’s really going on a clean new game, the problem is observed if the save matches the old version.
