>but it seemed the easiest solution (Occam's razor)

In my opinion, it only seems like the easiest solution on the surface taking basically nothing into account. By the time you start looking at everything in context, it just seems bizarre.

To reiterate, your assessment is true and we can assign it a low probability, but in the context of trying to explain why one model would be an outrageous outlier, manual intervention was the simplest solution out of all the other hypotheses, despite being admittedly bizarre. The thrust of the prior comment is precisely to caution against conflating relative and absolute likelihoods.
