I Know how to fix the fallen left arm, Inside the truck cab, Behind the windows, It has a .5x.5x.5 cube connected with a small rotator, Use the connection tool, Add a connection, Click in the small rotator, And click in the arrow, And BAM!, Your Optimus Prime is fixed. (If this not works, This worked for me) To save, Put the name as V2 Instead of V1.
