So my full set of power armor ended up in my inventory, and I can't use it anymore.

I can't equip it from my inventory, it says that I need to have a power armor equiped to use this.

I can't use the armor dock, it says that I need to find a power armor first before I can use it when I try the "craft" option (which is grayed out), even when I transfer the armor to the dock's inventory.

As to how it ended up in my inventory, well, I foolishly let my armor in a corner while looting around (to not waste energy just running around in full armor as I though the place was secure). It was quite a surprise when a raider attacked me while wearing it. Smart guy.

I killed him, and looted my armor. And now I can't use it.

If anybody has a solution, I would be very happy to read it
