for all versions SSG, do i have to use a set seed for every version?

yes

i mean you can do random seed and it still counts

but who would do that

if i dont have a set seed for all of them

oh but usually seeds work in other versions

for example 1.7 seeds virtually the same as 1.8 seeds

I mean you could just put whatever for the seed if you don’t have one

no

i would put any seed

then look where the fortresses are and stuff
