This is why we had a logger running in the background that received all anomalous events from warnings to exceptions (the class, method and passed data including passed parameters and the relevant line). And we had a catch-all trigger for when something goes really, really, really, badly wrong and there's nothing else available to dump to the logger. Annoying during development, a godsend in production. No one is immune from stupid mistakes.
