** Describe 描述 ** The plugin fails to load with the latest Slimefun and complains about the class me/mrCookieSlime/Slimefun/Objects/SlimefunItem/UnregisterReason not existing. I see #114, but am posting this here because the other issue has no info.

** To Reproduce 如何复现 ** Install Slimefun and ClayTech into the plugins folder Start the server

** Running Environment 运行环境 ** Tuinity git-Tuinity-"32b4d52" (MC: 1.16.5) Slimefun DEV - 881 (git dcc5648c) Metrics-Module #21 Java 11 Installed Addons: (6) ClayTech v1.2.21 InfinityExpansion vDEV - 103 (git 765f00a7) ExtraTools vDEV - 26 (git 0cb2ad70) IllegalStack v2.2.2a CMI v8.8.2.6 FluffyMachines vDEV - 79 (git 15a0fad9)
