Daybreak took an active approach today regarding the Test Server and actually asked and listened to the community regarding bugs, as a result they have decided to delay the patch to live by a day to tackle some outstanding issues, including tracking down and fixing another memory leak.

Here is the post by community manager Greg Henninger earlier today:

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.

Another update has hit the Test Server today, Battery has been lowered back to 300 again and First Aid Kits can now be stacked in the inventory again. Also, the recipe for the Flaming Arrow is now discoverable.

The masks we posted images of previously now have data associated with them, looks like these are possibly going to be the ultra rare items from a new crate.
