So both the Working Title mod to the CJ4 and the Salty mod to the B747 have a feature that means if you alter the flight plan in your FMC, it will amend the flight plan as created in the World Map flight planning tool - ie you enter a new SID directly into the FMC, then (in theory) the sim ATC will know that this is the SID you want to fly and assign it accordingly.
So my question is if the ATC bug of the co-pilot asking for new clearance every time you make a change in the FMC, is this an artefact of these mods, or are others experiencing it in other aircraft in the sim?
