I was playing the 10:50 to Arkham scenario earlier, and at one point I was instructed to spawn a random flying monster. But after the event was over, there was no way to interact with the monster that spawned in the app. How are we even supposed to fight it if there's nothing in the app to interact with?

This has been reported in the bugs thread at the top of this forum. I think the app is supposed to replace that text with an actual random flying monster from your collection, but it isn't working right now.

Hopefully a fix will out soon.
