User blog:Esoteric Arcane/Quarians during the data cache of ME3

I do not know if anyone else caught this, however a minor error in my opinion, is at the time you see the Quarian starting the war with the geth on their homeworld. They were wearing envornmental suits, not used until well after the exile and worn after generations of immunity breakdown occuring from being sanatized on ships. Why were they wearing it on their own homeworld?
