Hello! I ran into a bug today with shutters not remembering their ideal tool when breaking. Copper shutters were incredibly slow, and did not yield a drop upon breaking. Bamboo shutters were a bit faster and dropped their item form, but using an axe was no faster than using your hand. I am using Fabric 2.1.1.
(I figure not, but let me know if a log would help)

thank you i will try fixing it in the new update

Sorry for the delay i fixed the error and it is updated on modrinth and curseforge.

Thank you!! :D
