Talk about a confusing error message

I don't mind when I get told I've made a mistake -or there's a problem with the system but this error message kinda takes the P! Quite what the developers were thinking when they wrote this one I'm not sure!

What do I do? celebrate that it went through ok or commiserate because it failed?

The "Ok." relates to the transaction completing without an issue, the "Stop" actually says that it failed so it's not even "Part A was ok, but Part B failed". Really odd, someone needs to look into testing their system.

Looks pretty though!
