with POE's complex-specific-strict terminology, inconsistency and cloudiness are bad

Betrayal Scarab of Intelligence as an example:

-Betrayal Sextant mod 10 days ago:
% increased Intelligence gained from Immortal Syndicate targets encountered in your Maps.
- Betrayal Scarab of Intelligence today:
% Increased Intelligence gained from Immortal Syndicate targets encountered in Area.

Both are identical except for "your Maps" "Area" witch is neglectable cuz both apply to your map, so we conclude they do the same thing, and there was no mentioning of a change of this mechanic in patch notes..

Then I invest betrayal atlas point and play betrayal for 30+ maps, get exited that I got safehouse leader imprisoned and my shiny Betrayal Scarab of Intelligence on hand, go to map, find that it didn't work as expected, search patch notes and the web to find nothing but speculations from players, it is not clear if this a bug or a "hidden change".

This is unacceptable, introducing new things in challenge league and letting us discover is ok, but changing how a mechanic works "increased Intelligence gained from Immortal Syndicate targets" without changing the wording or mentioning a change in some patch notes or "New and Changed Scarabs" post, is so Frustrating and discouraging.
