Me A. Remnant scanner for peebee

I remember being frustrated by PB's "multi-part" story.

I especially remember wandering around a giant structure for a very long time trying to find what I was looking for.

I don't remember well enough to tell if it's where you're stuck, but there was a point where I walked to the opposite side of the structure from the nav point and found a hidden entrance to an underground area that was difficult to see.

If that's not the same place you're stuck, best of luck to you. A couple of the nav points are hard/tricky (and there may be an intervening step required to activate the nav point, like a mission that needs to be finished first, but I can't remember.)

If there's a big "mountain" structure thing, down in a bit of a valley next to what you're looking at, try climbing up and out of the underground section. Then try walking around the big mountain thing (to the right) and looking for an additional crack in the ground that you can't see from the side with the nav point. It wouldn't be all the way around, but about two thirds of the way and well-hidden.

My memory of it is fuzzy. The nav point was misleading, from what I can remember. It sounds a bit like the place you seem to be stuck, but it may not be.

It is a bit hard to tell which one of the Planet is this but i know for sure that Peebee got series of quests and all of them got pre-requisites. So you must do certain missions before you try to accomplish any of the Peebee's missions.
These are priority missions, one of them is called saving Scientists on Havaarl or something. One of these Priority missions are important to do before Peebee's mission is going to be automatically accessible, you got to progress in the Priority Missions first and save Peebee's Quests for later.
Here is my gameplay vid on Havaarl searching for the Remnant Scanner, watch it from 3:36, hope this helps.

it's in the same area wher you find the reincarnation glove thing for Taavos just look for the dead mercs. as it's in that area and across a bridge to a door.

I enjoyed the Peebee romance.. but holy hell was the lead up wayyy too much mission wise.
