Observing Summary:

Didn't open up until 1:30 due to high humidity and clouds.

One of the bolts on the RA preload plate sheared shortly
after opening. And then a second. And then a third. Decided
to home the telescope at that point and on the way there the
fourth came out and the plate dropped to the floor. This all
happened in the span of 45 minutes with not very much
telescope movement.
