Hello, I use the plugin VehicleAirdorp
When players throw one of these drops, they get a normal drop instead of a vehicle. and I get the following message in the conole:

[Supply Signal Alerts]  <color=#B404AE>Privater Airdrop</color> von AngryCougar!
Failed to run a 2.80 timer in 'SupplySignalAlerts v3.0.1' (NullReferenceException: )
  at (wrapper managed-to-native) UnityEngine.Component.get_transform(UnityEngine.Component)

  at Oxide.Core.Libraries.Timer+TimerInstance.FireCallback () [0x00018] in <beb2b64691c64e2b95b99491bd85442c>:0 

I hope there is still help with the SupplySignalAlerts plugin. Or maybe someone has another solution for it.
