I'm missing a few weapons from my preset list in game

For most of the guns, you first need to have them examined in order for them to appear in the preset list. You have examined one and its still not in? It's simple:

  • Examine the guns you want
  • Close your game
  • Restart the server
  • Open up back your game

That's not an issue, and is intended by BSG!

Regardless of this, you still have guns that still don't appear?

It might still be normal, as the most recent weapons might not appear because BSG didn't create presets for them.

There is probably a mod that adds it back at one point, but you will still need to wipe your profile get everything in the list.
