Hi, Looks like the swing collision body is falling asleep. Try in the component details panel→ Physics → Advanced to set the SleepFamily to “Sensitive” or to “Custom“ + set a lower CustomSleepThresholdMultiplyer than the default 1.0.
Another way is to create a physics material, set the SleepAngularVelocityThreshold very low or to 0.0 and set it as PhysMaterialOverride it in the collision section of your mesh component.
