The teleportation shrine appeared instead of the portal out of Eternity End portals.
I skipped the nether boss.
Floor 1324 exit shrine(supposed to be a portal out of timehole?) took me to floor 1325 and didn’t spawn the nether boss.
I can confirm this happening.
Are you (or anyone else) still experiencing this problem with the latest update? Just re-tested and it seems to be working correctly now but there might be some circumstances where it’s not.
