strange that the issue is happening again

This should not be the same problem, You can try it

Hello,

This seems to be working as expected from what I’m seeing, as setting an empty array to any value would cause an access violation, as it’s trying to set to a null reference. I would suggest setting up your setting in a way such as this:

but “Sprite Impls” connect “Sprite Interfaces” must be crash:

You’re still trying to set to an empty array. Sprite Interfaces has nothing in it, not even an element at the 0 index. You need to add to it instead of just setting it. You’re attempting to set a null array in this case. You’ll need to initialize Sprite Interfaces in some way before setting it.
