Stonecutters Complete Walkthrough

Does anyone know what to do for the last task with Homer and the stone cutters table? I have tried tapping him 10 times whilst he is doing the stone cutters table mission but nothing has happened. I am not too sure what else to do. Any ideas? Thanks :)

I too did the Facebook clues and I tapped him 10 times, it said I unlocked one more secret but nothing was in my inventory and no new tasks have come up yet. Anyone know what's the deal?

Does the Arc of the stonecutters do anything?

I am level 30 and have yet to unlock Agnes & Herman, I have completed all the other daily sacred parchments.
So I would like to know if the Arc reward does anything or gives a bonus of any kind, As it looks like I will need to spend 24 of my hard earned donuts to complete the daily parchment quests.

Any advice would be much appreciated, Thank you in advance.

It does nothing. No new tasks, no storyline. It provides no bonus % or anything, just helps with vanity.
