ToME: the Tales of Maj'Eyal

Hello!
I play steam version T.O.M.E on SteamOS. I chose an alchemist for my game, he use gems often, so I could see a mistake:
Gem "Jade" have not signed in gems list. Screenshot attached.
It is no problem, of course, but I thought, that I must write about it here.

Thanks!
Best regards.

The same issue is in this thread: http://forums.te4.org/viewtopic.php?f=42&t=42532

I'm so sorry:( I shall be watching topics more attentively.
