Edit: Wait, I will look it up properly.

Well i have checked on the net and it says the only place i can get Grade A Soil is at the Sin Gate can't access to that place yet, i have checked other places but can't get one.
My synth rank is A class

Edit: i have done the thunder dragon's quest, misanshel expedition and anti-angels items crafting.
Edit 2: and i need to upgrade the yard to get promoted.

You can't mine it yet, you can't get the recipe at current chapter, and you don't need to upgrade the yard at all to finish the chapter.

Do you have any open missions? And what missions have you completed in this chapter?

Ninja-editing our posts will do no good.

I mean missions, not quests.
Also, I think you have to fight off Misanshell invasion after this. Have you produced enough anti-angel items (3 each)?

Yeah i have produced the 3x items

Write down what missions from this chapter you have completed. I can check if you have anything else to do.

Also, I can't check right now, but I'm pretty sure that chapter advancement missions only require Store and Workshop upgrades. Could you check that again?
Edit: Indeed, says you only need Store and Workshop. Do you have 4500 Evaluation?
Edit2: Also, you need to complete the alchemist exam. Do you have its map opened?

Well from this chapter the only completed is ''Deal with the Misanshel''
And the advancement missions require yard and room too i have checked.
I do have 6677 evaluation points.

EDIT: you were right...i know what to do now, thanks for your help
