So, we're preforming a re-write an application. It's on an application (actual mortgage application, not 'app') that has 4 different entry points. We have the most common entry point converted to our re-written application with plans to have the next couple done over the next several weeks. Yesterday, the old version broke. It was under the impression that it could grab any row that matched the borrower and then check against a hash of that data to see if it could proceed. It can't. You can't hash data set 1 and expect it to be the same as the hash for data set 2. Not a thing. When asked, the only answer we could give right away was "We'll fix it, give us a couple of minutes" and "Sorry, bad {{appName}} is bad. We don't know root cause yet. We'll let you know when we do." Was pulled aside by my manager and told my answer was unsatisfactory and I shouldn't give answers like that. I get it, "Bad {{appName}} is bad" isn't great, but it's not like we were going to give that and leave it! We needed some time!
