Daybreak have just taken to Reddit to announce that tomorrows patch is being delayed until Wednesday. Sadly means you'll have to wait a little longer to craft your AK ammo.
Hey everyone!

Thank you for all your reports of bugs on the Test Server. There are a few that are proving to be more difficult than others. We want to make sure we nail these down and have a solid build for the Live servers.

We are going to be patching on Wednesday this week instead of Tuesday.
