Closing as won't fix: since you use 'move at angle' and the 8 direction behavior, you are causing a conflict. Setting the position effectively teleports the object, and then the 8 direction behavior notices it has been wedged inside a solid without knowing how it got there. This causes it to use a last-ditch "get me out of here" algorithm which happens to use a spiral search for the nearest free space, which in this cause causes it to move both up and right. Workaround: use 'simulate control left' instead and it works correctly, since the 8 direction behavior then controls the movement, knows where it came from, and can handle the collision correctly.
