Before the latest patch, I would play custom lobby games with bots and cheats enabled in order to do something specific, finish the match quickly and be able to analyze the replay afterwards. Basically I would do what I needed to do, buy 6 rapiers, and finish the game to get the replay. The game would always automatically save it to the "replays" folder as "auto-[match id]-[some random number]-[my account name].dem", so I didn't have to do anything to retrieve it. But since the latest patch, none of my replays are saved automatically, and when I try to download them using the match id, I would always get "Replay Unavailable" when I click the "Download Replay" button. So there's no way I can get them back.
Could there have been an option that was reset in the new patch, or did Valve completely remove this feature? I can't find any information on it.
