Weird, fleeting RT bug

Has anyone seen this?

I replied to a ticket using the web UI, quoting a
correspondence, and at the same time changed the
status field from new to resolved.

The stock “Notify Requestor on Resolve” scrip ran,
using the stock Global Resolve template which
includes the “most recent information about your request.”

Well the most recent information that was sent was
from another ticket!

I changed the status back to new and repeated the steps.
This time the template had no content, as expected.

This looks like a hard bug to catch. Wondering if anyone
has ever seen it.
