Geometry Collection Component + Anchor Field as Child Component struggles with high speeds

Hi, I need help with this one. Please help me!

Long story short: In my blueprint I have a super nice asset flip vehicle with a single geometry collection component (and a lot of other components) which is an armor that is supposed to break.

My vehicle is a custom pawn class with a physics simulated static mesh, moved by add force and add torque. I also have an anchor field as a child component. I know that a lot of people also had struggles with it, but my setup works. The white plates are the armor

The white wireframe spheres are my test-field-systems to break the geometry collection on certain spots. And its works quite well. From what I can tell, even my anchor field is working as it is supposed to.

But when I’m moving my vehicle at high speeds during physics simulations, the geometry collection is getting crazy when it is supposed to break. The whole thing is suddenly getting a very high offset, the anchor field isn’t holding anymore, and sometimes the whole geometry collection component gets this offset, while sometimes single parts are having different offsets although they didnt break yet. From this moment on, the motion blur is very strong on the armor, and it keeps the offset.

I am struggeling with this for weeks already so I have tried a lot of stuff like playing around with sleep thresholds and CCD and whatever.

What is this? Is this a bug? Please help me to understand the issue
