Zanzi gate doesn't show up

[a mammoth]

OK i put the zanzi gate into coag, spawned it using mach placement/palette combo, tested it showed up exactly where I wanted it and I was like awesome. So I spawn another one by adding a chunk to the mac placement reflex, move it in entity. I go test and only the one that I most recently spawned is there, the other I think might of been there but the instant I took a look at it it dissapeared. I also tried duping the zanzi gate and spawning it like that but that didn't work. So does anyone have any suggestions on how to get it to show up? It would be really awesome if someone could help me get this to work.
EDIT: NVM i got it
