I wanted to make a device that lauches small moving piston "missiles" but it looks like the "missile" after being duplicated with DRAY, don't works as expected. Even though, if I use one "missile" that isn't created by duplication, it works without problem. I think it is a bug as I can't find the cause of this problem.

This is not a bug. The real problem is that the mover itself uses a trick that's technically not supposed to work, but just sort of works. Cloning it with DRAY *that* way breaks that sort of working state. And yes, this means there is a way to clone it without its breaking. See below:
Oh okay. Thank you for your help!
