The Twilight Forest entities that use the "maze" category (Fire Beetle, Maze Slime, Pinch Beetle, and Slime Beetle) are all missing environments in-game, meaning they cannot be caged. This is because the item ID for the Mazestone Brick is incorrectly set as "twilightforest:maze_stone_brick" instead of "twilightforest:mazestone_brick" in src/main/resources/data/twilightforest/recipes/environments/maze.json (...environments/mazestone_brick.json in 1.20.2). This seems to have accidentally occurred when you updated the branches to mod version 2.0.1. The issue was fixed in 1.20.2 when you updated the Twilight Forest support on Dec 19, but the fix wasn't backported to the rest of the versions on Dec 11, meaning that this and all other changes made to mod on Dec 19 (like adding the trophies to the drops) were not transferred to the other game versions. I've attached a few photos; the first showing the missing environment within JEI, the second showing the missing Caged Mobs tab for Mazestone Brick, and the third showing the correct item ID in 1.20.1 (the version I happen to be playing).



Please note that I am too lazy to check if this is the correct item ID for the other versions. I would also like to apologize if this is confusing to fix; this is my first issue and I'm not too good at navigating GitHub yet, so some of my information might be incorrect.
