Problem happens with the supplied station and my own Shipyardtest on the testserver.
A simple 3 block station (shop + hull + build block) saves to local without a problem.
A more complex station did also save to local in the last pre release testing (although its logic didnt work after that)

Full log of one of these crashes: {F2417}
to reproduce
1. Load in this station to a Multiplayer server (local dedicated will do) {F2419}
2. try to take a blueprint of it with the save to local option
Note: original reporter claimed it was broken before the shipyard update... i cant confirm that
