Chapter 14: The Tragedy - S2-E6
Plot hole: Mando needs to make it to the top of the hill fast (he lost the ever important high ground, but he does not seem to mind). He would have a jetpack, but he left it behind. Now, everyone can be distracted and forget some piece of equipment and realise only a minute later (although it's a huge walk, and he has to climb, you'd think he'd remember right away). The problem is, even if Mando forgot the pack and realised only a minute later, the throwaway comedy intro of episode 2.2 showed that he can remote control the jetpack and call it back to himself.
Chosen answer: They could be just like wrinkles from age, like the elderly Togruta in the Zygerrian slaver arc in The Clone Wars series, as Ahsoka is considerably older than her animated appearances. I think there is probably a character design/stylisation aspect to it as well - the other Togruta we've seen in live action, Shaak Ti, has four segments or folds in her lekku that were not visible in her Clone Wars appearances, so it would seem the character design in Clone Wars and Rebels reduces such features.
