I am having an issue where the plane does not show up when supply signals are thrown.  The icon lights up for a few seconds then goes off, no drops ever come.  This has happened to me for a few weeks and only works directy after a map wipe for about a day.  Not sure if it's related or not but the heli spawns and is immediately destroyed and animals are spawning in dead.  Any direction to a resolution would be greatly appreciated!

Experiencing same issue, anyone know how to fix?

You must have something setup that is interfering with those plugins, I have this plugin and HeliControl running with no problems, I have InfoPanel and Inbound running with these plugins and indicators light up and I have the announcements in chat every time.
Can you post your FancyDrop config ?
