A motion making any of these defenses shall be made:
Motions and pleadings may be filed simultaneously without waiver of the matters contained in either.
No defense or objection is waived by being joined with one or more other defenses or objections in a responsive pleading or motion.
If a pleading sets forth a claim for relief to which the adverse party is not required to serve a responsive pleading, the adverse party may assert at the trial any defense in law or fact to the claim for relief.
If, on a motion asserting the defense numbered (6) to dismiss for failure of the pleading to state a claim upon which relief can be granted, matters outside the pleadings are presented to and not excluded by the court, the motion shall be treated as one for summary judgment and disposed of as provided in Rule 74.04. All parties shall be given reasonable opportunity to present all material made pertinent to such a motion by Rule 74.04.
