Here’s another thought. Do I use the Package Reorder Tool under General > Advanced Options to change when the Navigraph AIRAC Cycle loads?
Does it need to load first or does it need to load last?
(What is my age-old question, of course, is why this is affecting me and not others… sigh.)
EDIT:
Okay, I used the reorder tool to place Navigraph’s AIRAC cycle to load last and on cursory glance, it looks like it has resolved the issue, for now.
