Replaced the Imperial TIE Kylo took to Exegol with an Imperial shuttle, because ANH had made a point to establish that TIEs don’t have hyperdrives, whereas shuttles have been depicted onscreen as using them.
There was absolutely no indication that Kylo Ren had the TIE fighter jump to lightspeed from Kef Bir to Exegol.
Except that everyone else used light speed to traverse that expanse, including the crazy nebula (as they exit hyperspace when they come out of it). That’s an indicator, even if we don’t see the ship make the jump.
It’s not something that bothers me specifically, but it is definitely implied by the nature of every other ship that travels back and forth.
I do think it’s plausible that post ANH that TIE Fighters gained hyperdrives, especially since Vader’s TIE had it. It’s never commented on in canon other than in A New Hope, and we know it’s being developed.
