I'll try to break them down since they are a little confusing at first.
First there's the Vivarium, it's where any space amoebas, tiyanki space cows, space crystals, cutholoids, and voidworms go when you capture them.
To actually build(clone) any space Fauna and put them into your army, you need to cull a creature you've captured to get its genetic material further referred to as GM.
At the start you have space amoeba GM, which allows you to build space amoeba hatchlings that, after a set period of time(25ish years) grow into bigger space amoebas. You can skip this waiting period by researching destroyer class space fuana cloning(there is also higher tiers of research) which will allow you to just build bigger space amoebas and bigger versions of other creatures out right.
There is a rarity system to GM that goes from common-outstanding
higher rarity=better stats, you dont have to find the higher rarity ones, low tier creatures in the Vivarium can naturally make higher tier ones.

Snares cause crashes
Game crashed trying to capture a crystal fleet in the crystal home system. Will crash sometimes trying to capture other creatures but always so far for crystals. Recommend not using grand archive till the primary reason to have it is fixed. Really did they even test this ONCE? I mean come on the creature capture can be used early game and its broken so bad I restarted, loaded back in and it immediately crashed again.

Black Screened
Not sure if it's grand archive, cosmic storms, or something with this update but lost a late game save when the whole screen went black. Game is still running behind the black screen as I can hear everything but see nothing. Hope a bug fix comes out soon and the save isn't lost.
