Fixes Weird Area Definition on DeltaStation (tgstation#64986)

So, there I was. Pondering the blobbosity of Auxiliary Base Construction. Deciphering and unclothing the issue in my mind in order to better comphrehend it. I was there for a few moments, until this ugly beast of a fucking area definition caught my eye:

Hideous. Repugnant. I was relishing the thought of dissecting Auxiliary Base Construction into fifteen million more areas (it _will_ lessen obtusities) when that scraggletooth of an utterly mortifying error forced me into a visceral rage: the likes of which have never been experienced on this planet Earth.
