I tried setting up mixins in 1.8.9 and everything works perfectly fine in my Intellij modding environment. When I then compiled it to a mod however and tried to run it I crash due to a 'java.lang.ClassNotFoundException: org.spongepowered.asm.launch.MixinTweaker'. Any ideas what could be the cause? Here is the complete crash log: https://pastebin.com/yZdxDpEa

The version you are using is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.

Currently supported versions are 1.19.2 (Latest) and 1.18.2 (LTS).
