I would like to share the experience of running this theme on the new v0.12.1 - first of all, I absolutely
LOVE this theme, it's my favorite one!
It has a minor incompatibility issue right now with version 0.12.1 - the shop becomes partly broken,
you can't see the menu "Ask about..." and you can't see the menu with which you confirm your purchase.
However, it's easily remedied (until the theme is officially updated by its author) - you'd need to delete
the file "smallface.png" from the "Themes/MTGO" folder and the shop will function normally again. So far
this theme works normally with v0.12.1 after this small change.
