I’m not even surprised. I worked at a company whose bug tracking system was an excel spreadsheet mailed around. I’m not talking 2-3 engineers, I’m talking 250 engineers. There was one guy whose responsibility was to consolidate all the copies once a week. You can imagine how much information was lost there.
I put JIRA in there because even that was less shit.
Edit: also their VCS was a giant corrupted SourceSafe database as well.
