just downloaded and installed .70 crashed after about 3 turns on immense map - this may be hardware issue
the first thing i noticed is the old yor assembly (modified) seems really overpowered
previously it did .2 X (some derivation of your manufacturing) minimum .2 per turn as long as you had some manufacturing
now it does 1.0 per turn minimum. with assembly
this means first turn i can set my homeworld to 100% manufacturing, 99% military; and pump out a colony ship every 3 turns with 3 pop, and send it off to colonize new worlds, set them to assembly for the first 5 turns after landing and those colony's will each have 8 pop.
