Summary
After the 40.00 UEFN update, physics behavior appears to be inconsistent. In some cases, collision detection fails entirely, causing fast-moving objects to pass through solid geometry.

What Type of Bug are you experiencing?
Assets
Steps to Reproduce
- Open a UEFN project with physics-enabled objects
- Use a small, fast-moving object (e.g. a golf ball 20cm~)
- Apply a strong impulse or high velocity to the object
- Aim the object toward a static mesh wall or collision surface
- Repeat multiple times with high speed
Expected Result
The object should always correctly collide with walls and bounce or stop based on physics settings.
Observed Result
At high speeds, the object intermittently ignores collisions and passes through walls (tunneling effect), making gameplay unreliable.
