Easiest thing you could do is just desync the arrival of the 2 objects. Make one appear a few seconds later than the other.
If you can’t do that, you could attempt using Raycasting to find out if 2 objects have stayed in that position for too long, if they have then teleport one back a few studs something like that.
Or, you could make some collision groups, so the 2 blocks dont collide with each other.
Good luck
