Arena Battle without Spell Gems


version: 0.15.2 | Win 10 x64
EDIT: sorry it is 0.16.2

Well, I started an arena battle and that Lich Hellcaster suddenly lost all his spell gems in the first battle.
Check screenshot, please
(second image is for prove hat it is arena, see background)

What did I do?
I cannot remember to reload the creatures but it was a little bit odd that the Hellcaster gems were all Life spells like Blistering Radiance.
However, I thought I was lucky with properties. Afterward I realized you got rid of the properties in Arena Battles so it was suspicious from begin with.

Thank you for working on this one.
