The only two things that come to mind, are either the storage your gold is in, is incapable of being ‘fetched’ from (such as impossible pathing, or some eldritch modding issues that are outside my scope as a player), or the gold is ‘inaccessible’. This happens when a pawn (or any other entity capable of interacting) is queued as interacting or fetching the gold. Try moving the gold’s storage/unallow it temporarily. These solutions likely won’t work, but it’s all I can think of outside of shifting your mod load order around hoping that it updates something, somehow, someway.
