Describe the Bug

Going in either direction train conductors gets stuck in nether portal upon train arriving in dimension.
This seems to only be visual, train continues to function normally.
If seat is interacted with while conductor is stuck "Driver has gone missing" is displayed in chat and entity gets tp'd to seat location.
When entering dimension following error is displayed in console:
[Render thread/ERROR]: Error executing task on Client java.lang.NullPointerException: Cannot invoke "com.simibubi.create.content.contraptions.Contraption.setSeatMapping(java.util.Map)" because the return value of "com.simibubi.create.content.contraptions.AbstractContraptionEntity.getContraption()" is null
