It shouldn't have anything to do with the update. The event is available through the Journey Guide, not events. If you were finished with the requirements, you should have been able to see a countdown in Journey Guide (the Journey needs to be activated) prior to the start.
@crzydroidI also experienced this problem and missed executor. Did you have to have the journey active to open it. After I met the requirements I switched back to Kenobi, and never saw anything?
Yes, you have to activate the Executor journey and enter the event through Journey Guide just like you would for a Galactic Legend. After you unlock Executor, then the bonus tier shows up in the event section (and packs show up in the store).
