Thank you for the response. It is different from launch site but If I go into rustedit, I have breakable monuments, including launch site. I'm gonna try to break launch site apart, just take the helipad, and see if that works.
Okay, update. I used the breakable version of launch pad from codefling to save the helipad as it's own prefab identical to the original monument. So far I have tried both the new helipad on the custom monument, and just the launch site helipad on a 500-size bare map. I haven't found a way to get either of them to work. I'm gonna keep messing with it and it something works, I'll let you know.
