  The computation of one-loop corrections to the $\gamma^\star Q_+ q$ and
$gR_+g$ effective vertices in the framework of gauge-invariant effective theory
for Multi-Regge processes in QCD is reviewed. Due to consistent implementation
of the "tilted Wilson line" regularization for rapidity divergences, the
gauge-invariance has been preserved at all stages of calculation independently
on the rapidity regulator and cancellation of the power-like dependence on the
regularization variable is traced. Only single-logarithmic rapidity divergence
is left in the final result.
