Dainan
At this point, it seems prudent to wait until hearing from a GM. The warning posted (which I have never seen - maybe a Linux issue?) is a little too open to interpretation from what I see, and as a rule utilitarian it seems best to hear from "on high", so to speak, and get the matter clarified.
You can easily check whether the dialog displays on Linux, exit Ryzom, rename your interface_Dainan.icfg to interface_Dainan1.icfg in the save directory, restart Ryzom and enter Uni. That is the process I used to have the dialog reappear.
