[Possible Longstanding Bug] Certain lairs, often containing spiders and/or Butchermen, use up at least 2 movement when you defeat the guardians.
I'm sure it uses at least two movement, as with Master Scouts I can attack the lair but it uses 2 movement and I am not able to pick up the treasure on the same turn. This has been happening for as long as I can remember, even way back in the early betas.
Question to devs: is this intended, or is this a bug? I'm thinking it is probably a bug.
