For leaderboards from this day forward there is a rule change coming regarding uploading video proof for Project Kat and Paper Lily, the reason for the change is that twitch has added a limit on uploading vods and highlights to a maximum of 100 hours, from this day forward uploading runs from twitch will not be allowed on leaderboards due to the risk of losing and deleting them in the future if you exceed the given limit, if you have runs from twitch in other runs I recommend changing the link to youtube so your runs are not lost, more on this limit can be found here https://help.twitch.tv/s/article/video-on-demand?language=en_US#storage
