I'm trying out Zorro 2.20 free version (on mac osx). I've trained Z1 and Z2 and noticed both strategies end up updating Z12.par.
I've checked the original bundled Z12.par and it seems to include the parameters for both strategies, but when I retrain Z1 and Z2, Z12.par ends up with the parameters of the last trained strategy.
Is this by design? What would be the suggested workflow/workaround to train Z1 and Z2 on the same machine?
