In other words it still works. Note, it needs not be 100% accurate simulation. If it's good enough we can't tell.
Not that I think reality works this way, but the goal is to look for ways that a theory falls down, not look for evidence in support of a theory.
PS: FTL communication also works as a means to sidestep the need for a lot of quantum weardness. Sure, we don't like it but that does not mean it can't be happening.
