UpdateDrawablesWork Segfault Help [Solved]

Edit: Silly me, I have a component that deletes its node_ after some time, bad idea. I’ll have to rethink how do accomplish timed node deletion.

Hello, I’m clone()'ing some projectiles on TouchDown() and it seems to spawn and move fine but after a few seconds of movement I get a segault. Thanks for any help.

GDB backtrace:

What (drawable) components do your projectiles contain? What language are you using? If possible, post code and rough approximation of your objects, for example a prefab that uses bundled Urho assets, that reproduces the problem.

For timed deletion, it’s legal to call Remove() on the node. For example NinjaSnowWar does this when the snowballs vanish after a set time. Just deleting a node directly (C++ or Lua) is not permitted because that doesn’t remove it from the scene hierarchy and the engine will still try to access it.
