Hello, I haven't created a team yet. Everything I have in the datapack is also written above. I will try it again soon by creating a team and adding all Hostile Mobs. Because it didn't work for me in 1.21.11. So in any case not in the form I wrote above. Thank you for the tips.
I would like to have slabs that can be placed upright. In addition, it would be nice if there would also be slabs and stairs from the dark cherry wood, as with the pink cherry wood.
