🎉 Now it supports 1.20.80!
1.make the sit on stair harder to replicate on daily movement. Make it so u needed ur hand empty and u need to be atleast 0.5/1 block away from the stair or u need to be on top of the stair itself or u stand really close to it.
so i read the description of the addon again and it says that other addons that use the player.json files are not compatible...good to know
