Wynnexcavation Site A

Hello, I am doing the "WynnExcavation Site A" quest but when I try to complete it, Vade tells me to talk to Tesha and Tesha tells me to talk to Vade. I already killed the Pharaoh and left the chamber and my quest book says to "Return and talk to Excavator Vade" but when I talk to him it does what I said above...
This would be much easier to show with the video I made or screenshots but apparently I can't post links until I have 10 posts...

Please help!

 

Two things I can think of off the top of my head are:

1. You didn't pick up the crystal that the pharaoh drops or...
2. You missed a quest book update somewhere (lag maybe?)

It might not be a bad idea to go through the dungeon again and see if anything changes.

 

Go through the dungeon again and make sure to kill Pharaoh Nabak.

 

I killed the pharaoh, but I'll try again.

EDIT: Thanks for the replies btw
