Update!
I spoke with Jennifer at the Akron box office, and yep, it was a TicketBastard thing that completely blindsided them with the seat reassignments.
They actually have been hand re-assigning seats to make things as comparable as possible, but are having trouble b/c OF COURSE TM is closed today for the holiday!
She told me that they had to have a meeting this morning about it b/c they were getting inundated by all these messages from people whose new seats weren't remotely comparable.
So, they're doing their best, and may not even know until day of show given the workload and trying to work with TM.
FYI, Jennifer told me that the reason the show was moved was b/c the trusses at the Goodyear couldn't support DT's gear! In her words, "it's just too big!"
