Custom Faction Crash On Game Start

Posted on Friday, March 1, 2019

Every time I try to start a new game with a custom faction the game crashes to the desktop.  I'm opted in to the latest 3.5 beta patch.

I have tried creating a completely new faction as well as making a copy of an existing faction.  I have also tried creating during new game setup as well as in the faction creator.

I am able to start new games just fine with any of the default factions.

One thing I notice is that it always has the same lines in the error log:

Debug Message:  Building tech tree for node: GenericEngineeringTech
Debug Message:  WARNING: Failed to find tech specialization def: -1189087473

Is the editor not correctly setting up the tech trees?  Anyone know of a workaround?
