First time I see such a ridiculous evaluation :(
I think it was a mistake to use the crashed net when op (non crashed) is holding
the 24 point.
However, changing this requires a lot of work, because I have to rebuild a net
for both cases. My linux laptop has fried it's motherboard (only 1.5 years old,
out of warranty), so I am not sure when I can continue working on that because I
am not going to pay 2400$NZ to fix it when a new one costs about the same ...
