With the recent v20.10 update, the harpoon had to be replaced because of a bug. It's now replaced with the Kymera Ray Gun instead but not sure if it will be reverted once the issue is fixed. Also, the map now has infinite sprint enabled.

Going to assume that this will affect the leaderboard submissions with the new changes?

Yeah, I might split the leaderboard to have pre-version 68 to post-version 68. If the map gets updated again to remove infinite sprint, then I'll probably do something else
