You are wellcome. To put you in perspective:
Consider Navsystem.js as a core or shared file, to be read by all PFD’s, MFD’s, FMC’s, Garmin’s… If a modder makes a mod that contains a modified navsystem.js and doesn’t change the path to that file, it affects the rest of screens. Consequently, the affected users complain precisely to the programmers who are not to blame, or even report to Asobo a bug that is not their fault.
