Master Unit List Missing 'Mech Question

[Phaedros]

When I built a list a few months ago, the Loki and all of its alt. configurations were available to Clan Wolf/Wolf Empire in the Dark Ages. Recently however, I noticed the only Loki on the list was the Loki II, which is odd for two reasons. 1. It was there but is now gone, and 2. The Loki is prominently featured in the Clan Wolf Dark Age wallpaper.

Any ideas what may have happened?
