Would assume they have stopped taking MTO orders in favour of GMTOs and standard lines. They're still having problems delivering standard line shoes in a timely manner, stopping single MTOs should ease that pain, no?
You actually managed to change the colour of shell with polish? You must be some sort of demigod. If it happens again you should just be able to strip if off, shell is notoriously hard to dye, recolour etc due to its fibre structure.
