Update from the 24th of may not on steam.
 

As the title suggests, the update isnt on steam. This is also causing a lot of confusion on the steam discussion groups as no one has provided any sort of official explanation of whats going on aside from that the update has been released, which it hasn't.

The update will be available soon. We sent it to Steam some days ago but they must approve it first.

It might be worth stickying a post on the steam discussion boards to help with the confusion there. Got a good handful of upset people causing problems over it.

I agree. I have forwarded this issue.
