Glad you found it. Align screws up every now and then as well. The first batch of 500pros had the one way slipping as well. You had to take it out clean everything and green loctite it back into place. Also people were complaining that they had to use too many spacers on the new main shafts. So align jumped right out and shortened the shafts. Well now it looks like they went too far and some people are having trouble putting in the shaft without any spacers. lol!
