      Description

      The bug

      Attempting to save multiple debug profiles during the same second fails to properly save more than one profile. Instead, some are left as a .tmp file, like 2021-04-27_18.28.10.tmp.

      The following error is logged when attempting to save the second profile.

      Additionally, when trying to save three or more profiles in the same second, the following error appears, for every individual file that would be generated within the profile.

      How to reproduce

      1. Hold down the F3 and L keys for a few seconds (you should see "Profiling started" in chat multiple times)
      2. Check the game log
        The errors mentioned above are shown
      3. Check the debug/profiling folder
        Some .tmp files remain
