What steps will reproduce the problem?
1. Gather enough fragments to create an artifact
2. Type /archy solve or /archy solve stone (if you have keystones to complete the artifact with)

What is the expected output? What do you see instead?

In prior releases (before 7.0?) I was able to use the command to solve an artifact if one was available.  Currently I'm unable to input the command (pressing return does nothing).

What version of the product are you using?

7.0.3.11

Do you have an error log of what happened?
