I don't think it's a server lag though – it works perfectly with a pickaxe. And if it is a server lag, it has to be always lagging, because it always returns fewer blocks. Hmm...

I'm not exactly sure, but bug report?

I haven't had the same issue in both TC and IC2 Exp., so maybe re-install TC? It's possible that configs have been changed as well, check that out.
