I've got my game ready to go yet and I encounter CS0012 error upon building.
error CS0012: The type 'UnityEngine.MonoBehavior' is defined
in an assembly that is not referenced. Consider adding a reference to assembly
'UnityEngine, Version=0.0.0.0,Culture=neutral,PublicKeyTiken=null'
I'm using Unity 2018.1.9f1, building for Android 8.0 using Scripting Runtime Version .NET 4.x Equivalent, Scripting Backend is Mono and API compatibility level is .NET 4.x
