It's basically just me and RuffledBricks who are mods for WA, I'd love to have RRs as part of SRC.
The only issue is that I don't think we could include just any maps, since there are thousands (or infinitely many if we include random gens). A community vote on a small number of map packs might make sense. If we wanted to start by adding these Bonhert maps, I'd be interested.
So on those maps, the autosplitter is set up to stop when the worm loses its turn? Is it looking at the image of the timer in the lower left?
