Is Fire engine broken?

I can’t get the newest version of Fire (8.NN.MC.3) to work properly. It would go a3, then b3, c3, d3, basically it pushes all the pawns forward and does nothing else. All the evaluations return +0.00 unless there’s a mate coming, then it does see the mate. I’ve been testing it on 1 CPU, I don’t know what happens on 20 CPUs. The previous version (8.NN.MC.2) still works fine.
