When I had my first contact with B-Nine, saved & exit and load again, I always get a crash:

2020-07-07 17:36:16 GamesMage-4517.sav: System 3e: Unable to load object.
State: Loading object subclass
ObjectClassID: 100007

Can confirm this happens in different systems. As long as I do NOT dock to B-Nine stations, the savegames loads fine.

Working savegame with full debug.log attached. There is a B-Nine station in the current system, so the error could be reproduced.
a) Save & exit, load again - no problem.
b) Dock at B-Nine station (first contact), save & exit and reload again - error happens.
