[2021] Why did Smoke Bomb functionality get changed?

Returned to the game after a lengthy hiatus to find that the only means of fast travel is seemingly a bit broken. Previously smoke bombs' return point was locked until you used a service at another Temcenter or outpost. Now running by a Temcenter or outpost *sometimes* locks it there despite not touching services.

While I can understand the lack of a fast travel feature to a degree, I don't understand this change whatsoever. Intelligent use of smoke bombs was a fun game I played when I was TVing a new Tem or out questing somewhere, and now I just have to hope that I don't have to randomly waste 10 minutes running through a bunch of tall grass because my bomb decided to go rogue on me.
