Question

I’m getting a crash like this in my game:


ERROR: Unhandled exception

It happens at a point in my code where I’m cloning a complex graph of objects using FastCloner library.

How do I fix this? I’ve tried a couple of other deepcloning libraries, but this was the only one that fit my needs.

Managed to resolve this. Turns out that cloner library somehow didnt go nicely when it had to clone delegates coming from Godot classes. Worked around it by tuning which fields are cloned and skipping Godot class delegates.
