PC [BUG/HELP] Shook tree for golden walnut but was unable to collect it

[Randus]

I shook the tree next to Qi's place on the island, and the golden walnut fell off but wasn't collected. Now it isn't showing on the tree, but doesn't count as having been collected. Here's the completion tracker to confirm the issue.

Are you playing with any mods?

Was your inventory full?

Are you playing with any mods?

No mods, and my inventory had plenty of room- it's like the nut fell too far away for me to pick it up, and it never respawned.

Minor update: I've now collected 129 of them, and the bird isn't offering any more suggestions on where to look. Is there any way I can still get full completion?
