Block breaking "lagg" with faster tools mods

[omnee]

So I installed Metallurgy 2, and Treecapitator, and what happens is, when I break stone with a Metallurgy tool that is faster than diamond, it breaks the block, the block comes back, and after a short time, it breaks, with treecapitator happens the exact same thing except with every single tool, it breaks one block, the block comes back and the whole tree gets cutten after a while, now I know this probabily is a kind of "anti-cheat" for that super fast mining hack, but there also might be a way to disable it? If anybody knows how to, please, tell me...

 

Other info: This happens on server, I have the lastest forge installed and I have Treecapitator, Metallurgy, ExtrabiomesXL and FML (Ofc) installed.

Are you sure it only happens with the faster tools mod? It honestly sounds just like normal server lag to me, also I'm not certain what this has to do with Forge

The server side needs there equivelent of those mods in order to work correctly, there is no way around it.
