At first we assumed that it was mechanical for all but then we were in the store by the Haunted Mansion and overheard a Cm calling what we assumed was a higher up and they said "We need to open HM. Then get CMs from where ever, but people are getting angry!". Now I can't be positive of course, but it sounded like a staffing issue more than a mechanical issue. Which we found sorta strange-you have a special hard ticket event and not the staff for it??
Who knows-but it's disappointing either way, with what they charge for the MNNSHP to have 3 rides down for most of the night.
