I get this error in console, after the world has loaded and I started moving. It sometimes crashes, too.

That isnt a error, its a bug with the version of netty MC uses in 1.8.8, nothing we can do about it.

And is the crash related with the netty bug?

[LexManos]

No, they are not related.

As you are in dev world I can't say what the issue is because out line numbers dont match up.

However something is editing something that it's looping over in the update method, you should try debugging for yourself and see whats going on.
