[Added] Deep Chelsith question

[Leucosia]

While doing the prelude quest for BoL, I realised that the "Deep Chelsith: Vault of Omens" instance seems to reuse the map from "Chelsith: The Ancient Vault".

Old DB-created maps are exp09_dun_deepchelsith_ and exp09_dun_deepchelsith_solo_

New zones for "Deep Chelsith: Vault of Omens [Solo]" and "Deep Chelsith: Vault of Omens [heroic]" are exp16_dun_chelsith_prelude_ and exp16_dun_chelsith_prelude_solo_

Could it be possible to reuse the old maps? I don't ave access to the zonerect and original image files but I gather you have them?
