Artifact spawning and collection is now all but bug-free, some visual UI glitches remain but nothing major.
However, it is late here, and I need to get some sleep before pushing the patch live.
A new countdown has been set.
Once it hits 0 you will be able to find and open Treasures containing all manner of Artifacts. Clicking on Artifacts collects them to your Vault, which you can open from the menu in the top left.
