So I was just sitting here thinking about my holographic companion mod wondering how I can get it to work right, then it hit me; PUPPIES PERK!!!
Backstory on how a holographic companion from New Vegas has anything to do with the Puppies Perk: Before I even heard of RFCW i was working on a companion mod that adds in a "killable" hologram companion. The main issue I was running into was a feature I wanted to add that after the hologram "dies" it reappears after a few game days and rejoins the player. It occurred to me tonight that this is almost exactly what Puppies does for Dogmeat... SO off I go to see how it's done and try to finish that mod that's been years in the making.
EDIT: Well, it helped a little, but not enough. Just need to set a timer for the companion to be moved back to the player after 2 game days
