Mirage bug (cant finish mirage)

I have encountered a bug with mirage where i cant finish mirage because last 29 mob not in mirage zone. This includes djinn mobs that i need to release from chains.

I checked every room; cant see, cant hear them. Note: Boss room and harvest are so close to (partially inside) mirage zone yet not included in mirage area.
