So, what was wrong? Playing white, Critter encountered many times (25 or more) the following position:

r3kbr1/1bq2p1p/p1Np1P2/3Pn3/1p6/5Q1B/PPP4P/2KRR3 w q - 7 5

(sorry, I don't know how to build a diagram)

Every time, he performed the same moves, showing the same PVs, with Houdini making the expected reply, and having score falling after two moves. (Critter plays white)

5. Qf4 {(Qf3f4 Bb7xc6 d5xc6 Rg8g6 Kc1b1 Bf8h6 Qf4xb4 Rg6xf6 Bh3d7+ Ke8d8 Qb4h4 Kd8e7 Re1f1 Bh6g7 b2b3 Bg7h8 Rd1e1 Ra8g8 a2a3 Qc7a5 Kb1b2 Ke7f8 Rf1xf6 Bh8xf6 Qh4xf6 Qa5xe1 c6c7 Ne5d3+ Kb2a2 Nd3c1+ Ka2b2 Nc1d3+) +0.65/18 10}

Bxc6 {(Bb7xc6 d5xc6 Rg8g6 Kc1b1 Bf8h6 Qf4xb4 Rg6xf6 Bh3d7+ Ke8d8 Qb4h4 Kd8e7 Re1g1 Qc7b6 Rg1f1 Bh6g7 a2a3 Ne5xd7 c6xd7 Ra8b8 b2b3 Qb6a5 Rd1d3 Qa5e5 Rd3f3) -0.22/15 2}

6. dxc6 {(d5xc6 Rg8g6 Kc1b1 Bf8h6 Qf4xb4 Rg6xf6 Bh3d7+ Ke8d8 Qb4h4 Kd8e7 Re1f1 Bh6g7 b2b3 Bg7h8 Rd1e1 Ra8g8 a2a3 Qc7a5 Kb1b2 Ke7f8 Rf1xf6 Bh8xf6 Qh4xf6 Qa5xe1 c6c7 Ne5d3+ Kb2a2 Nd3c1+ Ka2b2 Nc1d3+) +0.73/14 0}

Rg6 {(Rg8g6 Kc1b1 Bf8h6 Qf4xb4 Rg6xf6 Bh3d7+ Ke8d8 Re1xe5 d6xe5 Bd7g4+ Kd8e8 Bg4d7+ Ke8d8 Bd7g4+) -0.22/16 1}

7. Kb1 {(Kc1b1 Bf8h6 Qf4xb4 Rg6xf6 Bh3d7+ Ke8d8 Qb4h4 Kd8e7 Re1f1 Bh6g7 b2b3 Bg7h8 Rd1e1 Ra8g8 a2a3 Qc7a5 Kb1b2 Ke7f8 Rf1xf6 Bh8xf6 Qh4xf6 Qa5xe1 c6c7 Ne5d3+ Kb2a2 Nd3c1+ Ka2b2 Nc1d3+) +0.10/15 2}

No scoring backwards here. Now, I know so little about this learning system and I cannot be sure on anything. Maybe, it's due to the "resolve score drops" being unchecked. But I guess a simple hash hit should have caused that backwards propagation, and that didn't happen.
