I get this type of error when any missile hits the ground or its target when CE and multiplayer are loaded at the same time. would there be any way to fix the compatibility? (for this error i used the disposable missle launcher, aka the M72LAW)

Exception ticking Bullet_M72LAW3488 (at (76, 0, 79)): System.NullReferenceException: Object reference not set to an instance of an object
