I think it may be time to add a checkbox "automatically send booking reference and last name to cowtool in the event of an error".

Clearly the whole tool isn't down since it's working for some people (and me), and short of having the failing ones, there isn't much to do. And it's always the same. Someone posts here that it's not working. I ask them to PM me. They do. Then I (try to) fix whatever's not working there.

I believe there are different error messages when it's definitely a bug in the tool, compared to "An error occurred. Check your input and try again.", which usually indicates an error loading the data. But when I have some time (probably not today), I'll verify that and add the option to automatically send me an email in cases where it's possibly a bug in the tool.

For the past 5 minutes (and next few), I am trying a few things that might result in intermittent failures though.

Edit: Not that it was failing for me at all before, but I'm done this minimal maintenance. The logs do indicate a couple errors had occurred recently, so hopefully giving it a kick will improve things?
