Somehow my CAP is somewhat buggered up. Before I explain the problem, I will mention that I was going to submit this to the tracker, but the bug is limited to this one CAP file. Anyways, on with the problem.
In the CAP(linked at the bottom), whenever I click on the "Add" button in the bone behavior editor, as soon as the mouse passes into the main editing frame, Construct crashes. I created a new file and tested to see if it was the same, but it worked just fine.
Bone Behavior Bug CAP
Any idea what's wrong with it?
