Cartographer's Strongbox with additional map currency not dropping map currency

I have had exact same issue as this guy https://www.pathofexile.com/forum/view-thread/3423840

Strongbox rolled the additional map currency modifier but didn't drop any. I don't have screenshot before it happened but this is what the drops looked with everything visible afterwards:



I assume it has something to do with the current currency stacking feature where you will usually drop currencies in bigger stacks instead of individual single drops.


EDIT: Fixed with 3.25.0d Patch

guess what strongboxes don't have to drop?

ANYTHING AT ALL.
