walker error

[Godji46]

begin
  Self.Name := 'Walker';

  minimapImage := Minimap.GetCleanMinimap();
  minimapSample := Minimap.ScaleMinimap(minimapImage, Self.Scaling);

  Self.Cache := TMatchTemplateRGBCache.Create(Self.Map.ScaledMap.ToMatrix(), MinimapSample.ToMatrix());
  Self.WalkUpText := ['Walk here', 'lk he'];

  minimapSample.Free();
  minimapImage.Free();
end;

Edit by slacky:
This references Simba 1.4 issue where the cache allocation

TMatchTemplateRGBCache.Create(Self.Map.ScaledMap.ToMatrix(), MinimapSample.ToMatrix());

causes "Invalid floating point operation".

Personally I have no idea why this issue comes up, but if this is unchanged in Simba 2.0 we could add some security measures so that proper errors are raised on bad input - now I'd assume a blank cache matrix (all white, all black etc) would be bad for example.
