When you click on the fit starter motor bay the game will crash every time.
This does not happen when clicking any of the other bays and is easily reproduced
The crash after clicking at the ‘Fit Starter Motor’ slot is maybe a result of a wrong part (Steering Wheel) requested to stock of this slot. As soon as the ‘Fit Steering Wheel’ slot is connected to the importer this crash will not happen anymore and the missaligned part will move to the correct station:
The reason for the missalignment is another point. Did you remove some ‘Resource Conveyor’ or a ‘Resource Importer’ few moments ago?
That point brings me to the question: What happen when a conveyor between a slot and its only available importer gets broken? Will the request cancelled or realligned to a different still connected slot?
