but it's fine on server, I wonder why

Fixed in 1.1.1

I deleted modid.mixins.json in the jar and it becomes fine, huh

Wow, I did not realize I left that in there... probably because of some issues in the dev environment that I tried to fix with the example mod... The thing is that those mixins should not be loading because they are not defined in the fabric.mod.json...
