In short, these are vanilla events leading to funny consequences.

The only mods are cosmetic, the checksum is intact, the game is on ironman and achievements enabled.

Started on Sol, with Terra.
Had a Parallel Universe event, which let me dedicate resources to save Terra-Beta from its universe's collapse and transport it safely to Sol.
Had the Hitito/Solarpunk random quest chain and they gave me Sol X to my system, which I named in a completely different system of counting as a joke.

i think it is ancient cache of technologies

What Mod is this? Also Gamma is after Beta.
