I found some bugs in that interface that took wind out of my sails. I emailed the company about it but the last update was two years ago so I'm not hopeful for a patch. They're obvious things that would shake out in testing.
Specifics sent to dev:
>I progressed to world level 2. At the beginning I did not activate the new artifact but instead went back to world level 1 via the map then went back to world level 2 via the map. This process removed the world level 2 alien artifact. If this was by design it would make map usage conflict with artifact progression.
>Also, a second bug is that when clicking "Activate" in the artifact section with no artifact selected throws the error.
