Well, for one, you’ll probably want to add _explosion to be a child of something ;).

#3

edited , app stops when it reaches this point

The app stops? Like crashes? Is there additional information (exception? Was any assert hit?)

#5

yeah it crashes and none , just the fatal signal

#6

Sounds like a fun future of debugging into the call to figure out where it crashes for you :).
