With the beta release, the map is not the same, etc. Backson already said it but there are now 10 chapters (3 more than before), in the leaderboards, and it still didn't get actualized, well still, for now, nobody has still done the 3rd chapter so the 8th... I don't think it will be done for a moment but still, if someone wants to try it it would be cool to have them.
And then so If the Any% for the beta is the 10th chapter and for the version 4.6 (4.5 and etc.) it's the 7th... the beta would be at a disadvantage, A real split of the two versions would be best I think like for Minecraft (Pre 1.9, 1.9-1.15 and 1.16+).
Yep, the maps/versions are not really comparable. I think when 1.0 releases, that will be the version most people (me at least) will run on. I was looking into trying a Chapter 4 run, but haven't gotten around to it. I guess new versions breaking the meta is a common problem in most games? To do it on separate leaderboards within the same game seems reasonable.
