Ok I just find one which is easy:
https://boardgamearena.com/archive/repl ... s=84207926;
Solutions were:
b min: 234-254
y min: 434
p min: 432-452
No information about blue or purple except C.
They test C on the yellow and it's wrong.
Then they test 452 sucesfully.
On that game, they did a weird choice by starting win the single solution, then tested 452 randomly over 254.
First, the start is weird. Secondly, they could assume they needed to take a coinflip to guess.
Maybe it's anomaly but from what you said it seem not. But that's very weird for sure.
edit: I want to add that after checking to 10 others games, that one was the only one weird. So it's totally possible it's a mistake from them, or a mistake from me writing the game on my solver.
