Can't load any track

[CrystalH]

Hmm,
Inside:
bool CARTIRE::LoadParameters(const PTree & cfg
cfg looks not empty, but begin() == end(). Thus cfg.DebugPrint() writes nothing here.
There is _value="tire-touring" but _children is empty [0].
But _parent has [49] _children (all the a,b,c tire params).
So this line can't find any tire param and fails:
if (!cfg.get(st.str(), lateral[i], error)) return false;
