I tried for 1.7.10 and it totally worked, but when I do it for 1.15.2, I can't choose the map in the 'Type' section, neither have any block in my inventory from creative mod (Is it supposed to work like that when you're outside the map ?). What's funny is that with the Jei mod, I can actually see the recipees for the objects included in the mod, and then the menu display is the same as the 1.15.2 (with the catchphrase kinda changed), and in the mod section (I'm using the recommended forge laucher for the mod), the mod shows up. Then I also tried removing the other mods from my carpet only leaving lotr, but yet the same bug. Does someone has some advice?
