Yes. My elephants clipped through a concrete barricade in front of rocks at the face of cliff barrier to smash the glass fence up at the top.
Sigh.
Edit: my bad, just noticed you were taking about anomalies clipping into each other.
you could work around that with making an onTriggerEvent that changes one animals direction when they touch. its not nice but a lot easier on the cpu.Issue is, with the amount of animals you can have in some enclosures, making it so animals can't clip would make the game even more CPU-intensive. Imagine a habitat with 500 flamingos. It's hard enough on your CPU already, but with collision-avoidance, even NASA would have trouble running it.
