I actually talked to the MC that said he caught the irregularity of the words Bishop Webster and because of that, they reconsecrated afterward.
Sorry, but I don't believe this. If they caught the "irregularity", then they had an obligation to notify Bishop Webster during the ceremony because the rest of the ceremony was improperly held with the assumption that Pfeiffer was already a bishop.
I doubt they caught anything. And, even if they did, given how difficult a time Bishop Webster had with the Latin, I don't have a lot of confidence that he got it right the second time.
