It is, as Paul Kelly above says, a fault with the data the TVM was using. We have sent RDG an urgent bulletin to address this.
Just heard back:
We have a staff brief on this already just going trough approval and should be out first thing in the morning.
We know the issue is caused by the TVM suplliers not updating the IDMS data feed into their machines in sufficient time before the sale started, but we have worked it out to around 180 instances if “TEST DO NOT USE” out there.
Meant to say, thanks for using us
