Start with nothing, build everything.
Large total conversion mods.
Map generation and terrain modification.
So... the Biter Egg Handling is only researched when capturing a biter spawner.
However, on Voidblock, there is no spawner, forever locking players out of Prod 3s & Biolabs.
Oh, right. I disabled all of the trigger techs that Void Block normally adds for Space Age because you don't need them if the planets are unchanged. Except for the biter spawner, of course, because that's on Nauvis.
Fixed now!
