im not really sure but i can no longer /reload my world I added overloaded compressed blocks (curseforge link) to my modpack then Dungeon Crawl started acting up. This is from the console when I /reload - Pastebin link

overloaded - 1.16.3-1.0.21 dungeon crawl - 1.16.5-2.3.5 forge - 36.2.30 other mods - a bunch but your mod worked perfectly until I added overloaded if needed i can compile a list
