[2021] Can't finish Boudicca Tomb... Tombs of the Fallen

Entering the tomb... I moved the first 2 pedestals into place successfully (1 on left side and 1 on the right side)
Jumped across the cavern to the middle section and turned left, climb ladder and stairs go into next section through hole in the wall
down hallway of wall spikes... slide across rope to platform and continue left WITHOUT interacting with the lever and picking up orb
move across platform past the turning spikes and over to the movable stone... moved into place and jumped over wall
Once of the other side of the wall, I MOVED THE SECOND MOVEABLE STONE INTO PLACE where I'm supposed to climb on top and throw the orb up on the ledge

Realized I was missing the orb so I circled back around to the lever and picked up the orb

This time when I go back to the movable stones, the second movable stone on the other side of the wall isn't there any more because I moved it. Now I can't jump over the wall because you need both movable stones on each side of the wall

Movable stones wont reset themselves to their original positions and I can not get over the wall any longer preventing me from finishing this tomb
What to do now?
