I think it is starting to come together, this thread and the barn, at least one of them.

The bracing effect of the barn is lost, it must have a lean in one direction, probably in the direction of the rotted tie? Is the wall plumb? I think back to assembling bents on the ground and things are moving right along and realize a brace has not been installed, we have to back things away to get the brace in, it has to come apart a fair distance, distorting the frame. This barn has done that.
