One Shell Cloth Too Many?

I was working my way through the solo version of the Field Guide for the Age of Ahnonay and started counting cloths. One on the water island, one on the stormy tower, one in space where the tower was = 3. One is each maint room = 3. One in the back corridor near the ladder and one in the last room = 2. 3+3+2 = 8, not the usual 7. In MOUL the cloth near the ladder is not there, so back to 7. Now I am working my way through Ercana, and will be counting the cloths again.

The field guides are meant to cover both solo and MOUL, so something for everyone no matter what happens -- I hope.
