Has anyone found a reliable way to find the data vaults with the blueprints for the Erlking? I've deployed about all the Adv. Sats I can stand and am still missing one of them.

Folks on the Egosoft forums came through.

If you've got Notepad++, open up your save and look for "elkring". Data vaults you've found will have two extra flags on 'em (something like "ownedBy" and "knownByPlayer"). If you set the owned clause to "player", when you load the game the data vault will show up on the map, wherever it's at (in my case the last one was way, waaay off from where I was looking).

I'm not sure, but this might mark your game as "modified", so if you care about that just look up the data vault coords in the save game without changing anything.

In a german thread on this subject in the Egosoft forum, a method with scouts is described if you don't want to have "modified" and don't want to build everything with satellites.

Thanks for the link! My friend tried something along those lines and it worked for him just fine.

In my game, that last vault was just ridiculously far from the original boundaries of the system. Three cheers for random object placement! >.>
