I've seen them put up normal updates (like the last Tidalis official version) the same day we asked, actually, iirc. Anyway, we'll see. I can't seem to get steam's forums to let me in, if someone could make a post over there explaining the following that would be great:
1) Steam's version of AI War is currently 4.021 (at the time of this writing). The current official version of AI War is 5.0, and that is supposed to be on steam now but there may have been some confusion or holdup, etc.
2) Light of the Spire doesn't show up if you're running version 4.021. It does show up fine if you're running 5.0.
3) If you're running into this problem then use the in-game updater, it can bring you up to 5.0 and you can then play LotS.
4) Sorry for the inconvenience, we don't know what happened, we'll try to figure it out as soon as we can.
