I believe that same thread you brought up in the OP (or another I'm thinking of entirely) also said that time still passes by even if no one enters.
Example: No one enters and citadel is closed for 3 weeks with no ticks taking place. Someone enters on the fourth week. The state of the citadel will be as if you missed 3 weeks.
Regardless if this "bug" is fixed, you can't actually pause your citadel so the point is moot.
