Please read what we post.
Edit: That is the 10th quest in Sobek. Use my link above and scroll down.
The quest giver is in your camp, if you have done everything correctly.
The checkmarks are for clearing all tiles in a location. You can still have quests unfinished.
I bet it‘s the GIVE MILK quest.
You can read it if you tap on the quest pictures that I mentioned.
Make milk in the kitchen of your camp.
Then you have to give copper. It says so in the quest picture and in the list that I linked for you.
If you don’t have copper, get it in the coal cavern (where is coal and copper).
And PLEASE when you ask something here in the forum next time, post your last location in the entry post! We invested so much time to worm that out of you 😉
First nothing at all.
Then Egypt only.
Then Horus only.
Then not Horus, but Sobek.
THEN the actual location.
As soon as we have that, we can help with exactly the information you need 🙂
