So, I'm having an issue with a forge map I am trying to build. I am utilizing the pressure plate mechanic, so that when you step on the plate, a container large comes out to block your path, and another one drops to open up a new path. But anyhow, the crates keep despawning and respawning again. I have tried to set the min count to 2, but that did not work. The best I can get it is to set the respawn time to 1, but that doesn't really help. Would putting a grav lift that is constantly pushing the boxes stop them from despawning? Any suggestions would be greatly appreciated. Thanks in advance!

Hey guys, I'm new to this forum (and forums in general) but I've been playing Halo since Halo 2 (I'm only 17) and I really got into forging in Reach. I thought I would join the forums to get some good ideas for forge, and maybe find a group of people to play some customs with, since all my of friends are CoD fanboys. ): I haven't actually picked up Halo 4 yet, but I hope to get it some time this week! So if anyone plans on hosting some customs lobbies let me know, I would be very interested in joining!
