This is just a complete dumb, uneducated guess based on things I pulled out of nowhere, but here's a guess as to what's going on.

Yesterday they probably had big meetings discussing the mountain of feedback and bugs to solve. That probably took between 0.5 and 1 days. Today, they're fixing bugs and maybe making other changes. This could take 0.5-2 days, who knows. After they've gotten enough done to make a new build worth it, then they'll do some in-house testing to make sure there's nothing game-breaking. There will be. It'll take another half a day to track down and fix the game-breaking bugs. After that, then they can update the alpha.

My guess is that they're still in the fixing bugs/making changes state, and are not at the point of having a new build ready to release yet.


And if you think the fog of war is an annoying bug, be glad you don't have the one I have that crashes games on loading 100% of the time.
