Now that there's Furier difficulty in speedrun mode, will that category be added to these leaderboards?

Most likely, though I'd say the best way of proceeding would be to wait until they make it out of the beta and into the public release. Though that's just me.

We could pretend the in-game leaderboard is official for the time being as the dodgy times haven't infested it yet >:)

If you ask me, I'll wait till it makes it to the public release. But when it's out I can get it set up if you so wish!

Fair enough. Thanks!
