ETX90 corrector baffle shift

I took a look at a friend's ETX 90 that had been stored on it's side and there is a cylindrical object attached to, but somewhat off center of, the corrector plate. I'm guessing that the this is a baffle that is normally centered around the silvered secondary-mirror portion of the corrector.

Has anyone else encountered such a problem?

The baffles on the ETX are known to shift if they are left in the sun, or other hot place. If the warrenty has expired on the ETX it's not too difficult to fix. Just remove the front lens of the ETX, pull off the baffle, re-align it in the center and glue it back down.
