There was this run on NG+ Santas Helper that had coop interaction where another player helped progress through the level (https://www.speedrun.com/rqter/run/z5j085jm), I had verified it at the time but after some consideration, I wanted the communities opinion (what little there is of it). Considering three options for this.

Option 1: Ban Coop interactions
Option 2: Make a seperate category for Coop interactions
Option 3: Just leave it alone

Also just a small thing for milliseconds.

Option 1: Enforce milliseconds on all runs
Option 2: Enforce milliseconds only on Top 3 runs
Option 3: Leave it how it is
