You have a set spawn of 5 objects, that are in specific locations always. These are not the same as other people's.
Talking with two friends, I only had one overlap with one of them, but I also had two items just 4-5 meters away from each other ( and fairly visible). Other parts were laughably hard to find.
I don't mind so much these being unique, but maybe make them get more visible/reflective over time as you spend a while in there, rather than having no clues. Since nobody can help you, some sort of light assist would be nice.
