IL2CPP crashes when two non-existing methods with same declaring types and parameter counts are referenced from a DLL with this callstack:

IL2CPP error for method 'System.Void PlayMakerFSM::NetworkSyncVariables(UnityEngine.BitStream,HutongGames.PlayMaker.FsmVariables)' in D:\Projects\unity\Runtime\Export\Rect.cs:14
Additional information: Object reference not set to an instance of an object.
il2cpp.exe didn't catch exception: System.NullReferenceException: Object reference not set to an instance of an object.
