When does one get points from Citadel approaches

Decept1on: So I'll try to explain a bit.   The rules to get the x4 FP for the clan for capturing an approach is only valid when you have the citadel, no citadel, no x4; if you capture the citadel, it is not retro-active. This means the previous approach captured will not receive the x4. Example: For a gold fortress, clan X attack approach A and win, the clan get 300k FP, the day after he attack the citadel B and win, the clan will not get the 900k (1.2m - 300k) retro-actively.   In other words, best tactic to get 1 approach, then the citadel, and then only after this, capture all other approaches.   @Kantii All FPs for fortress provinces capturing will be after next turn calculation. During next turn we are changing province owner and create task for crediting if it's fortress province.
When all our regular calculation (owner changing, battles schedule, results processing and so on are past) - we're processing FP.
