Crustle Puzzle: Confusion or Bug

[ChibiChi]

This is only the second thing I've encountered in this game I'd consider a "bug", the other being the Teddiursa event near the beginning. When I push the Crustle down the ledge that's necessary to get to Ametrine Mountain, by the time I get down to the level it's on to push it, it's vanished. Every video I've seen online and walkthrough I've looked through seems to indicate that I can complete the puzzle before I have Surf, just not get through the mountain, so I wanted to do the puzzle beforehand so I didn't have to go through this again when it was time to go to the mountain. (I'm not the biggest fan of this puzzle design, but that's completely an opinion and not regarding the issue I'm having or quality of the game at all, just personal preference that made me wanna get it out of the way ASAP). I am extremely confused and agitated, as the run from where you push it down and where you need to get down to push it more is a very long walk that I've had to do over and over again as I question why this thing keeps vanishing. I'm following the guise on the Route 2 Reborn page step by  step, and yet.............. Please someone just tell me if I'm somehow messing this up and getting it to despawn somehow, or if an update came out that doesn't let you do this portion of the puzzle before you get surf (which would make no sense, especially cause the wiki specifically states "You need to get to Ametrine mountain for the first time after acquiring Surf, but you can do this as soon as you get to Route 2." I can also guarantee I don't leave Route 2 at any point between the push and the arrival, there is no indication on my screen of entering another area. I don't even get into wild Pokemon battles. Am I supposed to take a route that doesn't have me go through the shortcut gate or something? I truly do not understand what I'm doing wrong here.

Adding picture of me staring at the Crustle after I've pushed it, and the very missing Crustle by the time I get to the lower ground.

Now adding a picture of me, a fool, realizing there's a WAY shorter way to get there by jumping down this ledge and to the right to the stone I can walk down and saunter over to it no problem. The guide on the Route 2 page does still say "Run all the way back to the entrance of the Route, then take the stairs immediately north of the gate towards Agate Circus. Follow the path until you get to the Crustle you just knocked down" for this step, which was in fact not working for me, so I'd like to leave this question up that I immediately found the answer to myself, in case someone else experiences the same thing.

I will readily admit, however, that with how long it took me to realize I could hop down the ledge, as well as immediately answering my own question as soon as I posted it, does make me in fact not just an Agate Clown, but the whole Agate Circus.
