As there are some objects/items in the game which are not so easy to pinpoint or that are a bit eccentric, some explanations might be needed.

Institute

Several objects can only be acquired in the Institute. As there are no hard references to any object in game to avoid Cell Edits, this mod cannot help you much if an object is in the institute until you go there. So, the marker in the world may not be exactly in the institute. If you have not gone there yet, it becomes even more odd. Nothing much to do about it right now. Though I am open to suggestions.


Prydwen

Some other objects are placed in the Prydwen. If it is not there at the moment you install this mod, it will show some nice markers in the middle of the sky. Again, this is a problem which I cannot do much at this moment for the same reasons as the ones in the institute. Again, I am open to suggestions.

Unique Weapons

As it is, not all unique weapons are exactly unique in the game, most of them are basically normal weapons with a different name and specific modifications. Meaning that there are no specific objects for them. That being so, the only thing I could do is to bring you close enough to the object while not fully tagging it.

What exactly does that mean?

It means that most of the Unique weapons markers will disappear once you get really close to it. Some others will point to vendors and disappear, meaning that you have to buy it. Others, like the Broadsider, have an unique weapon object and the marker will remain over the NPC which will give it to you until you fulfill the required quest.

Roaming vendor

One specific weapon can only be bought from Cricket, and she roams around a lot. The current marker points to where she stays selling stuff on Beacon hill. If she is not there, either return later, or wait until she does. The marker will disappear if you get to close though, as the weapon she sells is not truly unique and it is not possible to detect when it is acquired.

Alien Blaster

The weapon can only be acquired once a random event happens. If you get to the location and there are only molerats in there, return some time later to check or if you see the event happening.

Weapons with quests requirements

There are many weapons which requires a quest to be available at a vendor. The objective specifies which quests are needed. If you have trouble finding it, ping me in the posts section and I will help.
Some others it might happen that the NPC which owns it is not there at all. Still, in the objective name there is the info about the required quest.

Missing Weapons

Some weapons were not added to this mod. These are which weapons and the reasons why:

1. Final Judgement was not added because it might be available at 3 different places. I may add it at some point. But not right now. I believe his clothes will be also not available when I do the unique armor package.

2. The Reckoning requires a level 4 vendor, which is something that this mod cannot point to. It is quite trick to get it and the how to get it is not in the objective of this mod.
