Hi.
I have in Sanctuary build my own house, and placed all my power armors. They range from t-45 to x-01. One of each. (i am level 42)
I removed the fusion core's from them all.
I fast travelled to do a mission, and when i travel back to sanctuary all my power armors, exept 1, are suddenly T-45 ??

The last power armor is still x-01, but now without my modifications, pieces missing...
I load previous save, and issue still the same.
Also items in my crafted containers seems to be filled with ammo and junk.

Anyone had similar issue?

Haven't had it happen personally, but I've read about it happening to others, and have seen it in a video (in that case, a found set of X-01 changed to T-45 as soon as it was equipped).

Does it remain changed no matter what save you go back to? I mean, even if you go back to a much earlier save, are whatever PA sets you had at that point changed? Also, what platform are you playing on?

I've got a dozen sets of PA standing around at Red Rocket, as well as a toolbox full of unique weapons and armour. I'd hate to lose everything, but as far as I know, nobody has figured out what triggers it.

never happened to me.

I can go back to a previous save, and it is fine. But after I leave/return to Sanctuary the problem is back. 7 T-45's and 1 x-01 without modifications and random pieces missing.

I tried to modify the x-01 again, and leave the rest as is. It reset right back to basic after a travel.

Just throwing ideas out there... what happens if you go back to the save when things are still intact, leave Sanctuary (go far enough away to be in a different cell) and wait/sleep for 31 days before going back? I think there's something going wrong with the cell reset, and maybe waiting another full reset period might sort it out? I know I read about the "31 day wait in a different cell" trick sorting out some similar glitch, but I can't remember the exact details.

I read about similar issue in some mod's comments, that particular mod had to do with being able to remove clutter in Sanctuary. Apparently the issue itself is with the cell refreshing. While some mods stumble to it, I guess it can also bug out even without mods. In that particular case, people said it was safe if the armors were moved to some other settlement that was way out of the same cells where Sanctuary resides.

Now, I'm not saying this is the same issue, just sounds similar one. And most probably has to do with the cell refresh one way or another. Are you on PC and if so, do you use any mods?

Edit:
From Scrap Scrap
"Game have issue with CELL update. So when you change a CELL througth esp mod
game will reset stance of all preset CONT (containers) items. That mean
that all Power Armor Frames you scavenge in commonwealth will be reset
to their starting game values (mostly random), but all Frames bought
from merchants will not be affected.
Also every game feature tied to cell will also glitch like hell.
That is not a mod bug. That is a game engine bug.
So if you want to use this mod make sure to preserve your power armor mods."

**The Cell Reset Bug And You**

This particular bug is a very well known side effect of ANY plugin that changes a cells world space. What causes the bug is currently unknown and it's possible it cannot be fixed until the release of the official modding tools.

This bug causes all non-player made furniture and containers to reset themselves as though it was the first time the player had entered the cell. This includes power armor, as frames are considered furniture by the game. Also for whatever reason, cells affected cannot be sprinted in until crossing between it's border and an unaffected cells border.

-Work Arounds-
Store your power armor on only store bought frames, these do not appear to reset.
Store your gear in only player made containers.
Remove any non-player made furniture and containers from settlements to avoid having them reorient themselves and respawn their contents.

Note that using the INI setting does not cause the cell reset, only using the Cell Enabler does."

Hi again!

Just to update you all, it seems that the mod Scrap Everything was causing the cell reset issue.

Uninstalling the mod and loading previous save solved the problem.

Everything is now working as normal again, and my power armors keep the modifications i give them, even after traveling.

btw. the tip with buying a frame did not solve the issue for me.

Thx to Alisu for suggesting the scrap issue.
