NullReferenceException at OnServerInitializedError

I recieved a random error today. 

Failed to run a 1.00 timer in 'QuickSmelt v5.1.3' (NullReferenceException: )
at (wrapper managed-to-native) UnityEngine.Component.get_gameObject(UnityEngine.Component)
at Oxide.Plugins.QuickSmelt+<OnServerInitialized>c__AnonStorey0.<>m__0 () [0x00010] in <81c963c471ba4906ba6008cd47bd0962>:0

at Oxide.Core.Libraries.Timer+TimerInstance.FireCallback () [0x00018] in <12678b905a6d43c3a9cc366104306651>:0

Any ideas?
