Anti-Break not working 1.10

[tenten8401]

Trying to break blocks (claimed or unclaimed) on 1.10 yields this error:

Thinking this has something to do with the fact that players now dual wield.

[Arckenver]

Indeed. It's due to the fact that Nations 0.x versions are targeting v4.x.x of SpongeAPI.

To use minecraft 1.10.2 compatible versions of SpongeForge/SpongeVanilla (SpongeAPI v5.x.x), please wait for versions 2.x of Nations. Those will be out when SpongeAPI v5.x.x won't be bleeding anymore (at the same time as v1.x of Nations).

Can't wait until it's updated! Might fork it and give it a shot myself, although I doubt I'll get far as I'm fairly new to this whole sponge thing.

[Arckenver]

Can't wait too ! Thanks for your interest in Nations.
