[Out of Bounds in the Plains of Eidolon]

Okay so I was in my archwing fighting when I got shot out of it by a troop transport ship. Instead of falling to the ground I began running hundred of feet in the air without losing altitude. Needless to say I immediately took advantage of this and I managed to get past the gate and found out that, in fact cetus was actually behind it, albiet untextured and missing a few things. Next I went to the tower to get a closer look. In similar fation it was rather untextured but still pretty cool. I'm still currently floating around and I was wondering if anyone had any ideas where some out of bounds Easter eggs may be. 

[Trying to build some things but I can't get resources.]

I have been trying to build a few things and since about two days ago, I started to notice that, despite the fact that I have been picking up these items, my total amount hasn't increased. I have noticed this in a few resources that I have maybe 3 to 10 of since it's hard to tell with over 100 (These include mutagen and fieldron so far but some other resources like argon crystals and neurodes to name a few).  What's more is I cannot find these items anywhere in my inventory. Despite this, I know how many I have, or even that I have any at all, because my foundry shows me that I have them in certain blueprints. I'm kind of worried to build anything at this point because I might have to start prioritizing what I can build before my supplies run out for good.

If anyone has experienced this and/ or has a solution to it, please feel free to comment below. 

I'm not sure if this is a bug or just a result of a full inventory section (which I doubt considering I already have the resources so they should be able to stack)
