I get the follow error every time the event runs: Failed to run a 1.30 timer in 'AirfieldEvent v1.5.2' (ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index) at System.Collections.Generic.List`1[T].get_Item (System.Int32 index) [0x00009] in <f98723dd4586469db5213ec59da723ca>:0 at Oxide.Plugins.AirfieldEvent.SpawnDrop () [0x00790] in <a2958370943646c980a391f3c29c1b34>:0 at Oxide.Plugins.AirfieldEvent.<ChangeSpeed>b__109_0 () [0x0000d] in <a2958370943646c980a391f3c29c1b34>:0 at Oxide.Core.Libraries.Timer+TimerInstance.FireCallback () [0x00018] in <d59b507fd76240e5b62228d0eae39b73>:0 Assistance would be appreciated, thanks. AirfieldEvent.json

It worked for a little bit, but then it began preventing cargo ship, patrol helicopter, and supply drop events from occurring. I had to disable the plugin in order for these to occur again. Any help would be greatly appreciated.
