Referencing an custom indicator - Could not load file or assembly

I am building a cBot which uses an indicator pzSupportResistance (in cFractals.algo). This pzSupportResistance internally uses another indicator ZigZag (in ZigZag.algo). I do not have the source code of either, I use the .algo files, so I am using the #reference directive.

In my code, I can initialize and use the ZigZag indicator without any issues. (I do not need the ZigZag indicator, but I tried to make sure dependencies are fine).

However, when I try to initialize the pzSupportResistance indicator, using the following statement :

_cf = Indicators.GetIndicator<pzSupportResistance>(6, 24); 

I get the following error :

Crashed in Initialize with FileNotFoundException: Could not load file or assembly 'ZigZag, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.

It does not crash, continues execution but obviously the _cf indicator is not initialized.

1) I have verified that both the indicator algo files exist in the Indicators folder.
2) I can successfully load the ZigZag indicator, so there is some issue with referencing in cFractals.algo of the ZigZag.algo file.
3) I have set the AccessRights to AccessRights.FullAccess, but still no luck.

I would appreciate if anyone can point out the cause of this issue ?

cBot code (bare bones);

    public class MyBot : Robot
    {
        private ZigZag _zz = null;
        private pzSupportResistance _cf = null;
        protected override void OnStart()
        {
            Print("Initializing ZigZag ...");
            _zz = Indicators.GetIndicator<ZigZag>(12, 5, 3);  // INITIALIZES FINE
            Print("ZigZag initialized.");
            Print("ZigZag = {0}", _zz.Result.LastValue);  // RESULT IS CORRECT
            Print("Initializing pzSupportResistance ..."); 

            _cf = Indicators.GetIndicator<pzSupportResistance>(6, 24);  // CRASHES

            Print("pzSupportResistance initialized.");
            Print("pzSupportResistance Support = {0}", _cf.Support.LastValue);
        }

        protected override void OnTick()
        {
        }

        protected override void OnStop()
        {
        }
    }
}
