When trying to creat a special terrain with mithril for a town, in this dialog, 1 mithril will be drawn (with no info pop-up) even if nothing was selected, which doesn't makes sense to me. There should be a "I change my mind" option here for safely quit.
So I can't stop getting confused seeing these two options. They both makes artifacts more useful, but seems to be different from their names. Unitil I heard from daemon that these 2 options are actually "Enhanced Artifact I" & "Enhanced Artifact II" in Rus WS - that makes much more sense. I think the English menu should be renamed in this way too.
I apologise for only able to reply in English. I hope this doesn't result in any confusion. :D
