This isn't exactly a bug, but it seems like things are not working the way they are supposed to in the Delaying Action (3rd) fight in the Defense of Woodhome module. I have typically sent one guy to stand of the victory square and left my other two guys where they started to play terrain attachments, etc. as the armored skeletons run at me. Except that rather than run at me, they like to pass early and often, so that what I imagine is supposed to be a tense, desperate attempt to hold them off turns into a matter of hitting "pass" a few times and then winning. I ran into this on my playthrough on the testing server with the latest balance tweaks (so version 2.65.2), but it has happened to me pretty consistently the last bunch of times I have played this scenario.
It certainly can happen randomly, but perhaps the weighting of the various action choices is wrong. I will take a look.
Hmm, I wonder if an opening pass while still standing on lava should be fixed? Absurd behavior? Yes, but it can be a real time saver.
