Err, no. It's just...extremely early alpha. Dev textures are always used for early alphas, if not alpha all the way into beta.
Anyway, A1A is up now. Changes in zee changelog.
Also, I may be completely restructuring mid, now that I think about it, I really don't like having it inside a building after-all. More than likely, _a2 will use the "new new" mid, once I think about how it'll look.
