Hero dead doing her duty

I just sent my hero and some troops from one town to another to deal with the monsters there ... and my hero died. It's fairly clear that while the army passed thru the monsters w/o interaction--I've seen that happen in the animation--she couldn't: When her path from the entrance to the town intersected them, they automatically fought and, unsupported, she died.

Is this an intended result? I accept death as a penalty for incautious traveling that the player can control, e.g., between fishing spots. But when you send a hero to a town, you can't control her trajectory, and death seems inappropriate to me.

What do the rest of y'all think?

The report is 1,163,747 in case that will assist the developers.

sounds like an old bug has reappeared.

Update: Resurrected her in the hometown, sent her back to the monster-breeding town, fully expecting that she'd run into the same fight and have to be re-resurrected.

This time she survived.
