I think you don't understand what Patch Z is versus the Test Patches. This is the official one to the whole community. You helped Scawen develop it by finding the bugs in the Test Patches. It's not supposed to have more than the last test patch.
Any idea when you signed up for the updates on the site? Trying to figure out why some have recieved and some not, May 21st is when I signed on for updates.
Is there any proof of this speed of updates, or just conjecture? Sure it's got more money and manpower, but afaik there's no proof of it's developement.
