Lonely marble blocks

Hi guys,

I have a quest named "Golden field"

It contains two parts - pay 200 wheat from your storage, and I did this one
The second is - Produce enough Lonely Marble Blocks to obtain 50 marble.

I visit my Provision house and use the function in the third line - the last there - Lonely Marble Blocks

Made several of them - don't remember well if I did it 5 or 6 times

And the counting bar on the quest list didn't move at all...........It still says 0/50 and already had passed 2-3 hours.....

What I did wrong?

Try logging out and back in and/or clearing your cache. Alternatively - is this a guild quest? If so, please check if it's an active quest or a waiting one. You won't be able to complete the waiting one until it becomes active.

It is a waiting quest in two parts in the same window..........I did the first part and is green now.
On the same window is the other quest for the lonely marble blocks........
Anyway - it would be because is waiting quest
