Can't progress - no 'cornycorn' in shop
The woman in the saloon tells me I need to buy something called a 'cornycorn' from the shop. In the shop the shopkeeper tells me this 'cornycorn' is available in the specials section. But when I go to the specials section of the shop there is no 'cornycorn'. I have tried uninstalling and reinstalling the game twice, but this doesn't fix the problem. The 'cornycorn' does not appear in the shop. Please help.
My phone is a Moto G5 running Android version 8.1.0.
