I’m receving this crash every time I’m turn on the Receive collision events V 1.1 .
The receive collision events is using the default settings.
Using the version 1.0 it doesn’t.
My burst count is 1.

I’m getting the same issue. You ever find the cause of issue or a work around per chance?

Ah, figured it out. You need to add a “Generate Collision Event” on your left Emitter instead of Location Event for your right Emitter to properly receive collision event.
