Royal access chamber error

i had this room placed but not near to the queen's room. just some normal pathways room link to this Royal access chamber room. and when i reach there, it says Royal access chamber needs to be connected with some rooms?
what kind of room it needs ? and btw this room never displaced after reaching. so i cannot replace it after i complete the temple.
wired.

first time report a bug, pls let me know what infor you guys want to see
