Guys, I need your help!!!
Irina absolutely refuses to move through the basic city portal.

I had a similar issue with Irina: she had learned a magic skill (water magic defense), which at some point stopped being active in her skill book, as if she had cast it and could no longer use it ever again...
I think it's a similar situation; the problem, I think, is that the game isn't resetting the skill's cooldown counter, but there's not much I can do to help. You could try experimenting: if she's not a mage, give her the Architect skill; she probably won't be able to use that either, or any other skill that can only be used once per turn...

But this is just for fun; in any case, we still have to wait for a patch.
