Everything has a way to be fixed buddy, don't be that pessimistic <3this is just a bug, just get in a kit and die. There is actually NO way to fix it (i believe) how the bug works is that the damage turns from a normal fist to a diamond sword with sharp 1. So instead of hitting for half a heart (without armor) to like 4 hearts
i don't think there is a way to recreate this bug since it is random just like the grim reaper bug and this one.ill try to recreate the bug if i can (i dont think i can)
