The Immured Fury does not appear in maps where he should

Ran two maps where the map should contain The Immured Fury. He was nowhere to be found. And yes, i turned the maps up-side-down attempting to find him.. :(

im having the same problem, suppossed to see him in two separate maps and same thing, i searched entire map both times like multiple times and couldnt find him either

Same, first map i thougt it was a single time event bug, but this is the seocnd time in a row, that i have a map with immured fury and he doesn't appear, monster count says 1 remaining, but he is nowhere to be found, walked around the map 4 times, for like 10 minutes
