5.0.2 Chaos Bug? - Physics constraint broken event not firing

I’ve got some stuff set up to reinitialize a physics constraint on a physics asset when it gets broken due to it being linearly or angular breakable. My problem is it only sometimes notifies the code that it’s been broken causing fun skinning problems to occur as seen in the video. When it gets stretchy is when it does not notify the break to anyone.

Does anyone know why this might be happening? While I do have custom stuff to reinitialize the constraint on a skeletal mesh nothing else has been touched so to repeat what I have done I’d imagine all one has to do is set up a scenario of breaking a physics constraint while listening on the on broken event to test themselves.

UE 5.3.2 physics constraint “On Constraint Broken” event is not working at all.

In my case, the event seems to sometimes randomly fire, but it’s less than 50% of the time it should or so.

I am also experiencing unreliable firing of “On Constraint Broken” events. I noticed this almost two years ago and it is still not fixed. Is anyone from Epic reading this? Please respond if so.

Did you find out anything more about this? I also experience this on 5.4.2

Is there another way to replicate constraints breaking or do I have to do it completely manually then? Like looking at impact force on bone or something?
