I have been working on this project for days now because it seems Solidworks has a mind of its own and keeps messing up all my mates (often I will open it up and my distance mates will have flipped direction even though they were fully defined). Now all of a sudden some of my braces have become out of place. I highlighted one and noticed it was missing a mate between one of its vertexes and an edge of another part. I tied to manually move it by dragging it and the computer froze. So I tried to re-ad the mate but it won't go into place. I was hoping someone could have a quick look at it for me and let me know what is happening with it. You'll notice the braces that are out of place compared to the others.
