Just a problem i ran into last night, but it's essentially a bug that deletes your time on the last level you played when you exit straight to main menu from completion of any level, in a speedrun this would be Boardroom.
Adding up the times of individual levels in chapter select before exiting to main menu showed that it was 2 minutes slower than what it actually showed at the main menu. Returning back to chapter select revealed my time was blank for Boardroom.
This may be common knowledge for some, or even all of you, and i'm not sure if this affects PC players, but this is on the latest version (1.06) so i would imagine it would effect any PS4 Runners. Adding up to times for each chapter is tedious but it would provide more accurate times and rectify this issue.
