Describe the Bug

Assembling a train under certain circumstances can result in an invalid contraption, resulting in a permanent soft-lock, instantly kicking every player in the region with no way of returning.

This behavior is present both in 0.5c and 0.5d Patch 2.

Schematic:
arbetart_g.nbt.zip

Reproduction Steps

1. Build the train schematic on rails using a schematicannon.
2. Use a station to begin construction of a train.
3. The server will create an invalid train when you attempt to assemble, irreversibly soft-locking every player in the area out of the server.

Expected Result

A train should be assembled.

Can’t reproduce, please test patch G.

I can load the schematic fine, I have heard no other reports of this issue, and many things have changed since patch C. considered fixed until proven otherwise.
