Endless loop in Eternal labyrinth

Currently stuck between sepulchre halls and a secret passage in a forgotten reliquary zone in Eternal labyrinth. The secret passage from reliquary zone goes back to the hall. The hall only goes to the reliquary zone.

There should be a path to a silver cache but it's nowhere to be found in the sepulchre halls. This is the first section after the initial Izaro fight. Have I missed something in the reliquary zone or after I used the secret passage. Or is this a bug ? I really don't want to waste another fragment and have to restart the lab again. I've already wasted two today because of lag and disconnects.

Look carefully.

Never mind. Seems I missed a passage after navigating some traps :-0

Thanks Shagsbeard. It does pay to look carefully indeed
