I had a bug report where my save was actually bugged so I thought "this is a good time as any to attach the save file" until I discovered I couldn't. Just left the report as it was and continued playing. A little later, they ask for the save file in response. Turns out, I don't have it anymore as it was but a quicksave. Could've saved that save I guess, but I got the impression they just don't want your save files in general. Luckily, I figured out how to reproduce the bug and got back to them.
