Spent 2 hours last night (leaving an hour late) with the IT guy hunting down a problem that affected at least 12 other teams. It didn't crash the app, but did prevent MANY scripts from working, and thus nothing could be committed.
I found the culprit, made a solution, and posted in the email chain my solution. (it required a code review and a client-side update)
Someone responded asking for another dev to confirm my report. That dev did and them dumbed it down for those who can't understand programming talk. Then EVERY EMAIL after that thanked that dev for "fixing the root problem" and "solving their scripts".
And just now, the PO for the bug was replaced to that dev's team. (previously was my team's PO)
