Maybe someone has any ideas?

Hi, !

Firstly, you’ve made realy great work! I’ve downloaded the plugin for physical grip, but found many interesting things in it.
Unfortunately, I occured a bug that crashes the editor (2017-10-10 commit). I’m not sure about what causes the crash, but it always crashes when I use OnChildGripRelease on specific blueprint. Also I’ve detached my bp code from release event to be on the safe side, but it didn’t help.

Upd: Ok, I solved the problem. Collision complexity was set to “Use complex as simple” in my mesh. Everything works fine after setting “Project default”. But still it looks like a bug.
