Trying to complete level 50 farming quest. I need to make 10 special pie mushroom crates. Cannot make them in mushroom factory nor imperial cuisine or imperial trade. How do I make them?

Fairly certain they're in mushroom factory. Check other city's factories though, might be like the costume mill where different ones have different costumes to craft. 

Ok thank you. I can make them at a level 2 factory in Grana. All very convoluted considering the quest starts and finishes in Altinova and the games own knowledge base says it is a level 1 product.

You can also make them in Valencia city. I took the liberty of also having a look for you. They're level 1s, as well. 

Made mine in sand grain

Thanks folks
