Sorry about this. So it appears to be a unexpected hickup with the Bitpay <> Ticketshop backend. I have tested the ticketshop by buying with BTC as well and it took about 1.5 hours for confirmation and then nothing happened.
We have contacted the ticketshop people. All sales have been recorded and it is just that something API-wise might have changed.
Ultimately it will be fixed by monday, but I hope sooner.
NP, im sure it will get sorted monday
