Getting issue when two objects at the same place

[RocketRoad]

I'm building a system that really needs to put two object at the same place. They are not colliding, in fact the first doesn't even have a shape. How to resolve a problem?

Ok. I figured out that it was due to spring with rest length 0

Ok, great. Then Ill close this one.

But how to solve the issue
I mean I can place object at different places but what if their position become same again. I kind of understand why that happens, like spring doesn't have direction to pull or push. But what can I do about
Just hope that probability of their position being same equals to zero?

Ah, sorry. Let me reopen this again. I dont have a quick answer right now.

I don't need the answer anymore. Just avoided using such constraint. But probably adding checking for such low probability is probably useless and can significantly affect the speed of execution
