The owerworld map seems to treat Conjurer and Troll Shaman as invisible. I'm not sure if this is intentional (they have this trait on purpose), or a bug. The game also tends to mis-draw other things (it looks like something and turns out to be something else).

Even if Conjurer and the Troll are "invisible" on purpose, this is not very good for gameplay - it can affect saving games when you're unaware that you're just about to get jumped. Also, if you manage to beat enough Conjurers and Shamans for them to start running away it makes it difficult to spot them and chase them down if you want cards from their decks.

I have occasionally seen them appear, but most often they are invisible.

Can anything be done about this?
