I believe regular Developers have the ability to fix the following bugs.
Dairy Churns currently do not function. They are required for making butter for cooking items such as Tuna Potatoes.
The entrance into the Wheat field north of Ardougne. There is currently no way into the field. This is the best place to collect wheat, as it is very close to a mill and a bank.
Using a Pot of Flour with a bucket of water or jug of water should give the option to make either bread dough, pizza base, or pastry dough. Currently, it default makes bread dough without the interface with the three options.
There are no shopkeepers in the Bandit Camp in the wilderness. This is a popular place to purchase pizza base.
