Bug: Won battle but location blighted and survivors not fighting

We won the battle at (75) Stormylake on map Blight of the Immortals. However the location was still blighted, and now there are Undead Goblins overlapping with Trolls, but he Goblins aren’t moving and are not fighting. They aren’t under any buffs other than their latent Lurking Terror.

Thanks Hegemon, I’ll try and have a look into this soon!
