It's not a gremlin and at the end of the day it's probably a misconfiguration or bug somewhere but it doesn't help anyone to point fingers and blame. A system probably went through a design phase, why didn't the reviewers of the design didn't catch this? The implementation was probably reviewed by peers, why didn't they catch this? It might have gone through QA, why didn't they catch this? And the list can go on and on. At the end of the day a mistake was made and it should be fixed but being enraged doesn't help anyone. Figure out what went wrong, how to make sure it doesn't happen again and do it.
