I don't see the message which happens when I can learn an ability from demon because it is hidden behind tooltip for current spell.
It happens all the time. The game ignores everything except y/n/escape. Probably the problem is specific for my computer since other players don't seem to experience it.
Windows 10, resolution 1366x768. It didn't happen with version from October (no changes on my local happened since that time).
Edit. So for me the game looks like frozen, and when I press Escape I finally see the message the game was trying to show me.
