Sry for double post, but would not allow me to edit my previous post.
My question is if anyone knows of a console command to teleport Rex or any other companion to player character. There are some for Fallout 3, but would need ID for companions.
1) First thing you'll need to fix this problem is to get a hold of your companions "reference ID" number. This can be found several ways. Easiest is to look it up on the wiki page. At the time this was written, there still isn't a whole lot of information on FNV Wiki yet, so you might have to use a different method. Load back another save, find your companion, and and open up the console. This can be done by pressing the ` or ~ key on your keyboard. Next, click on the companion. At the top it should say:
"[Character name]" (xxxxxxxx)
Copy that number down.
2) Open the console in your current save file. Type in:
prid xxxxxxxx (The reference number of your companion)
At the top of the screen it should come up with the name of your companion, and then their ID number.
Then, type in:
moveto player
Some text should appear, saying "[companion] picked package guard ()"
3) Exit the console, and your loving friend should be standing/floating/haunching/drooling nearby!
An example, say Rex went missing. I would get his ID number, which is 0010d8df, open up my console, type in
prid 0010d8df
moveto player
Don't remember where i found this
