In all local low-dimensional models, scaling at critical points deviates frommean field behavior -- with one possible exception. This exceptional model with``ordinary" behavior is an inherently non-equilibrium model studied some timeago by H.-M. Broker and myself. In simulations, its 2-dimensional versionsuggested that two critical exponents were mean-field, while a third one showedvery small deviations. Moreover, the numerics agreed almost perfectly with anexplicit mean field model. In the present paper we present simulations withmuch higher statistics, both for 2d and 3d. In both cases we find that thedeviations of all critical exponents from their mean field values arenon-leading corrections, and that the scaling is {\it precisely} of mean fieldtype. As in the original paper, we propose that the mechanism for this is``confusion", a strong randomization of the phases of feed-backs that can occurin non-equilibrium systems.
