Salt flats's bones delivery quest appears flying in bql

The pile of bones you have to deliver in hoodoo that should be in salt flats or in the lake's water was flying above the big quill lake's water.

I saw the stack of bones flying above instead of being in the water and when i took the last one the delivery point appeared in hoodoo like it should.

The pile of bones is supposed to be in salt flats or in the water of the lake and not flying above the big quill lake's water
