Some important things I should probably mention, first the starter picker thing will cause you to instantly lose the game for some reason and you do need to go into advanced settings (like the mod said) to actually pick it, the twins are actually in the mod they are just behind the NUC factory, and the mechanical summoner unit.

how do i change my faction at start of a round? im stuck with the normal one

I mean Mini-Twins

also what is mod that includes enraged wandering eye

Wspaniale sniwuś, życzę ci powodzenia w dalszym rozwijaniu moda :)
