Windows 10, Unity 2019.3.5f1, Arcadia 268bed0fc9dc5143870259d88a142d60ae8b7f9d

Given the following code:

(ns user
  (:use arcadia.core)
  (:import [UnityEngine BoxCollider2D
                        Debug
                        GameObject
                        MeshCollider
                        Rigidbody2D
                        RigidbodyType2D]))

(defn init-player []
  (destroy (object-named "Player"))
  (cmpt- (create-primitive :quad "Player") MeshCollider)
  (let [player (object-named "Player")]
    (log (cmpt player MeshCollider))
    (cmpt+ player BoxCollider2D)
    (sets! (cmpt+ player Rigidbody2D)
            gravityScale (float 0.0)
            bodyType RigidbodyType2D/Dynamic)))

When calling init-player in the REPL, it responds with:

System.NullReferenceException: Object reference not set to an instance of an object
  clojure.lang.Reflector.SetInstanceFieldOrProperty (object, System.String, object)
* user/init-player

  clojure.lang.Compiler.eval (object)
* clojure/core/eval
* clojure.lang.Var
* Arcadia.NRepl+EvalFn coop/Assets/Arcadia/Editor/NRepl.cs (203:6)

The Unity Editor Console logs the still available MeshCollider:

then complains about me adding a BoxCollider2D to a GO with a MeshCollider:

same with the RigidBody2D:

and finally: because the RigidBody2D couldn't be added I'm trying to sets! a nil:

Weird, I'll take a look
