Citi Field ticketmaster drama

I have no idea if I'm alone in this but is anyone else able to see tickets pop up, get to checkout screen (that should mean the tickets are "reserved") and then once you click pay/checkout- error pops up and says you need to pick different tickets...WTF? Its such an emotional roller coaster... :( and it seems to always be for the july 19th (sunday) show too..?
