Just as a side-note: You can still confirm this at the end of the file
using:
check account("Assets:Checking").all(account =~ /Expense/)
However, this will not tell you where the problem came from. That's OK
if you are actively using version control and can identify which set of
changes introduced the problem, but otherwise automated transactions are
the surest way to find the cause.
