I've seen this happen on real gameplay, but the easiest way to artificially reproduce this is to Destroy a critter the moment a Rhex jumps up to pounce. In real gameplay, this probably occurs when a critter dies or when a baby grows up to an adult. Given how often Rhexes attempt (and fail) to pounce on wild critters, this crash can become quite frequent

Steps to Reproduce

1. Destroy a critter right when a Rhex pounces on it

A developer has marked this issue as fixed. This means that the issue has been addressed in the current development build and will likely be in the next update.

That also happens if multiple (say 20) predators are targeting the same prey. Can reproduce it.

Note the HuntPredicateTame part because I put 20 tamed rhexes and 1 poor wild regal bammini.
