I encountered this glitch recently and its preventing me from completing the quest since the ECHO fell through the floor, here is a picture here showing where it is
Have you tried saving & quitting? If that doesn’t reset the echo then you can’t complete it.
that worked, it reappeared on the other side of the map, thanks for the help
I had something similar happen - the echo went clean through a floor, and reappeared on the other side of the map also. Looks like someone had that happen during testing and said, “Hey, we need to make sure we catch this one!”
