When I create a selector combinator using a method to instantly blueprint it does not function. Zero output and the settings are not saved (I select an option, close the UI and its reset when I reopen the UI).
I have replicated this using both creative mod's 'instant blueprint' setting and the blueprint sandboxes mod. I can not replicate it using /editor.

The selector on the left was placed normally and is functioning. I then copied the left selector using ctrl-c then pasted it to the right, with 'instant blueprint' enabled, it does not function. I have to remove it and replace it to get it working.
