Yesterday I updated the server and supply drops were working.  This morning I installed oxide and then installed Raid Tracker (admin tool).  After that no heli/supply drops are spawning.  Anyone got any troubleshooting advice? Do I got uninstall/re-install something?

Oxide doesn't do anything or even touch that without plugins. So either your configuration or a plugin would be altering that.

any idea where that config would be..?

It would either be from a setting or one of the plugins you have installed. You'd need to remove to test, and verify your settings.

any idea where that setting I could of messed up to supply drops?

If the time is being changed at all, that can affect it.

Thanks for responding Wulf.  Struggling on what to search to troubleshoot this.
I haven't changed time at all, only mod I have is raidtracker.

Have you tried without Raid Tracker?

would good troubleshooting steps be remove plugins, then run validity check of files or something?

If i run the supply.call it will come but it just won't randomly come.  The attack heli still randomly does though

my server doesnt spawn airdrops or heli too

my plugins 

when did airdrops stop working for you?

since this wipe

also my server cfg

nav_disable false
nav_wait false
fps.limit "256"
server.saveinterval "300"
server.secure "true"
crafting.timescale "1"
airdrop.min_players "1"
server.pvp true
sleepers.on true
truth.enforce true
server.clienttimeout "2"
env.timescale "0.1"
env.time "12"
env.daylength "55"
env.nightlength "15"
falldamage.enabled true
cheaters.log true
player.backpackLockTime "0"
server.steamgroup
maxteamsize "1"
antihack.flyhack_protection "1"

I'm having this issue as well on both of my servers. If a players deploys a supply signal or if I run the admin command to call in a drop it works fine. But on the automatic regular airdrop events the plane never flies over the map. The supply drop spawns instantly under the map and just keeps dropping down never to appear on the surface. I removed every plugin and the problem still happens. Even created a fresh server without umod on it and tried 2 different map seeds and still happens so I think it's a game issue. Never had this problem before and I changed nothing with my game files from last wipe.

Anyone help troubleshoot this?
