AI War 2 is a GO! Thank you! Here's what happens next.
Aww man! This level changed several times during beta, and so certain things became impossible in 2p it's clear. I should have done a better job of checking it, sorry. I'll get that in the morning; unfortunately it's rather late now. If it's blocking you, you can crack it open in the level editor (it's level 014 I think) and then switch to background placement mode and just right-click one of the haybales. That will get you past in the short term.
This was fixed on March 25th, 2013, actually -- in version 1.005: http://arcengames.com/mediawiki/index.php?title=Shattered_Haven_-_Beta_Release_Notes#Official_1.005_Stantonsburg.27s_RevengeIt sounds like you haven't run the in-game updater. If you click the play button, then you'll see a thing that says new updates. It's a really straightforward process to walk through that, and it updates a number of things as you can see in the above release notes.Cheers, and welcomes to the forums!
