Sulfite scarab not granting more sulphite

I ran a corrupted Forge of the Phoenix map with ~120% quantity. I added a gilded sulphite, cartography and strongbox scarab. In the map, I found three sulphite nodes but each of them gave only the non-boosted amount of sulphite (1.3k-2k). It is very clear that the boost from the sulphite scarab did not work (I've previously gotten ~5k per node in similar maps, including just today).

The map was under elder guardian control, but I've ran a similar setup (with only sulphite scarab + 2 sac fragments) for Pit of the Chimera minutes before and it worked properly there. I should also add that I switched characters after opening the map...

Oh, and my hideout instance died after I went back into the map for the /bug. I can't leave the map without logging out ¯\_(ツ)_/¯
