Red Errors

Hiya. I got the following when adding this in and I've no idea what it's about. Is ti something I need to worry about, and if so, is there a way to fix it?

Error while instantiating a mod of type DontShaveYourHead.Controller: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> HarmonyLib.HarmonyException: Patching exception in method null ---> System.ArgumentException: Undefined target method for patch method static System.Collections.Generic.IEnumerable1<HarmonyLib.CodeInstruction> DontShaveYourHead.Harmony_PawnRenderer::Transpiler(System.Collections.Generic.IEnumerable1<HarmonyLib.CodeInstruction> instructions)
