There is an issue with pmmp since 3.9.3/3.9.2, where Mojang released 1.12 and pmmp changed SLOT_ITEM to something different. I have not yet figured out how the fireworks work in 1.12/1.13, and due to lack of debug symbols i can not retrieve the information i need via decompiling. I am hoping for anyone telling me how it works now tbh.

Can you try out https://github.com/BlockHorizons/Fireworks (Poggit: https://poggit.pmmp.io/p/Firework) and tell me if it works? I currently got no access to a client
