3D Foin Creature Pack1 Issues in 4.8

So I’ve been using this package from the store and when I upgraded to the 4.8 engine the animations started crashing my editor. I’m starting to notice a lot of assets on the store are compatible with 4.8 is this a problem with the creators or Epic haven’t to verify that they are compatible? Is anyone else having this kind of problem? The package I mentioned was brought over to the 4.8 version of my project when I upgraded.

The condition that causes the crash occurs when I use my AnimNotifyState BP in the animation to trigger the visibility of the creature’s damager “collider”
