Solved

Just completed my first temporal sanctum dungeon.
inserted an unique ring with 2lp and an exalted ring with 4 affixes, clicked the button…
all that happened was that the machine closed and both items are gone.
no new item to be found, disabled lootfilter - still no item.

been waiting for 10 minutes now next to this machine…
i guess i can leave and cry?

Thanks

You have to switch to the far future for the “Eternity Cache” to work. Did you hit D again and check the Ruined Era Eternity Cache?

oh, that is likely my mistake then… could’ve been explained better ingame tbh…
But i guess that’s it - thanks for the info
