Stack of relics and lighting bug

[Note that this is a continued file with a "black room" bug]

On day 70 as Wigfrid, upon finding the royal pig village there were 8 to 10 Lost Idols and Totems in a pile just sitting on the edge of a sidewalk. When I had picked them all up from the stack, the spot where they were stacked produced what looked like 2 oval light objects. When I rotated the camera these objects were flat. Pic included, which has been sized down from 1080p.
