We've run into an interesting problem where one particular job just refuses to run on Sundays. This is not a new job; it's been working fine for years now. In the past month, though, it has simply stopped running on Sunday nights despite being set to.
As you can see from the screenshot below, it is set to run on Sundays and yesterday was a Sunday. The last time it even attempted to run was 3/1. It did not fail or even start on 3/4 as it should have.
(sorry for the large size, but it was unreadable otherwise)
