You need heroes for this battle, but i don't.

Every once in a while, I’ll start an ‘essential node’ and I will receive a message indicating I don’t have the essential char, when I do, for example:

Selecting Beast at this point doesn’t help, it puts him in one of the side positions. Usually, going out and back into the node will sort it out, but sometimes this takes a few goes. Wondering if anyone else has experienced this bug?

I had the same issue this morning, however once I closed the app and re-started it, the problem went away.
