Here's a recurrence of an old classic.
If you spawn a new station then unload the sector the station turns into a 10X10 slab of red hull.
Good times.
Only seems to effect new stations that only have a single block. If you add a couple of block to it, it saves fine. Does not effect ones you spawn from BP, or modified pirate/derelict stations.

How to reproduce:
# spawn a station block
# unload sector
# reload sector
# it should be a 16x16 (1 chunk) red hull plate now
As soon as you add a block to that station, it saves fine.
