Halo TMCC halo 4 Forge Not letting weapons spawn

I seem to be in a rut here, I’ve built a Flood map called Alien on The Master Chief Collection Halo 4 forge and when I play the custom game none of the weapons show. I know that they do on Halo 4 itself because I made a map called Just keep Driving and it worked all dandy and good, now this isn’t working. Just looking for a response to this trouble I am having. Please and Thanks anyone.
