Simbrief plan mismatches in MSFS, AIRAC issues?

Hi,
but to be clarify, this has nothing todo with SimBrief, Navigraph, or any other flightplanning tool. This is a MSFS “feature” - in that moment, when you change anything on your plan, the plan will be automatically re-calculated …

This is an official long term wish and is included in the the TOP-WISH list:

… but this “feature” will be hopefully removed with SU6 :slight_smile:
