This feature was accepted as an upcoming feature April of last year, so don’t count on it being added any time soon. 11 months now and it’s still missing.
It’s stated in the 3.45 status thread. Basically all traps were made server side in today’s maintenance so it can no longer detect them without a sight pomander triggered.
Still works fine with bronze/silver/gold/mimic chests and hoards, but no longer for any kind of trap.
