Is it a change? In v1, my Cellus System shows it as a non-flat asteroid belt. But in v2 it shows as a flat asteroid belt (I knew this problem before, but thats when I didn't use US1 very much). Im just asking though.
1st: Cellus C's Asteroid belt/proto-planetary disk in v1
2nd: Cellus C's Asteroid belt/proto-planetary disk in v2
