Despite me sounding like a bit of an a** last post, I do sincerely hope you get your Grape Purple, no matter which way you take to get there.
I'm not too sure this will work since you used the simulator last time. But, I hope it will, and I'll do my best to help you.
From what I see you went from Wine Red to Abyssal Blue to Loam Brown, Correct?
Let's try Pineapples for one feather message in attempt to back you up to Wine Red. Weather that works or not, we'll work from there. If It works, then Pears from Wine Red to Grape Purple hopefully. If it doesn't, we'll figure something else out.
