UStruct not permitting variable-like binding in state trees

So, first off, yes, my UStruct is - to the best of my knowledge - all present and correct. I have a native make function, even. Most of the native UStructs I tried also didn’t have good behavior when I tried to bind them. No error is being thrown, nothing is exploding in the logs. Has anyone run into an issue where their structs just wouldn’t work with State Trees?

Update: I checked, and it seems like blueprint as a whole doesn’t have this problem with my structs. Just State Trees. I’m gonna assume it’s something I need to manually add via an editor module or similar, but if anyone knows what incantation must be performed, I’d love a hand.

Update 2: I’m going to take a look at StateTreeBindingExtension in the plugin’s editor module. I’ll report back if I find anything. And yeah, maybe I am just using this as a rubber duck. Whatever. Someone in 4 years will find it. Hello future.
