Sorry, I meant to remove them from the participants list (or cut/paste them to the "broken bots" part at the bottom). There are 1112 bots total. If you look at the rankings sorted by number of pairings (), there's the 4 new bots by you and Cyragia at the top (with 1099 or 1104 pairing), then a few more between them and the bots with full (1111) pairings. So those bots are not getting battles vs the new bots, I guess. I thought it would be easy for whoever is actively running a client to see which bots are unable to download and go ahead and remove them. Or maybe they are available from Rednaxela's archive, if you feel like digging around to fix the URL. I'll try to get to it soon if nobody else does, but I don't have a rumble client setup right now.
I cleaned rumble there were a couple bots which my client cannot download. But there were a couple which report "an invalid robot or team". I have no clue what it means but I tend to blame my client, since they are downloadable and there were some relatively fresh pairing (month old) for them. But I removed them anyway, since de facto I am the only one persistently running battles.
I did not change anything in melee, since, right not, it looks like every bot have a pairing wiht another one.
