Ok, So I got my safe that I made to appear in my house, now I made a special suit of armor and a weapon, :gun: I had my safe loaded in GECK, made my armor and wep, put them in the safe, saved it as a new save, and it doesn't appear in my safe in game, It says Safe [Empty]. It is an active mod, it loads after my safe but it doesn't appear. :brokencomputer: I just modified the ones in the GECK via the GECK. I had emptied the safe earlier and then decided to create more stuff to put in the safe. The safe has its own .esp and the new things have their own .esp loader after the safe.

You can't just load two esps in the GECK and transfer items back and forth, those changes won't stick once you save them. If you want the guns to appear in the safe, you'll have to get them into the same mod together. One way to do that is to make your Safe mod the active mod while you load both at the same time. Make a change to the name of the gun from your other mod and when it asks you if you want to create a new entry say yes. This will add create a new item which gets added to your safe mod.

OK, I'll try that

Another way to do it would be to turn one of the mods into am esm, so that it can become the master of the other mod. In Fallout, you can't have an .esp file become the master of another .esp file.
