Crash when attaching thrusters to prop spawned objects

Hey! I wanted to know if anyone else noticed the problem of the game crashing when you try to attach a thruster to the second prob spawned by a prop spawner. For me, the first one works fine, but once I try to attach the thruster to the second object, the thruster falls off and when I click again to try to attach one the game freezes. By the way, I’m using the “useful and explosive” objects.

Thanks! Kevin
