Phased through the wall in my bubble escalator & fell to my death

So, I was going to follow my friend down my bubble escalator to my mining hub. They went down and then after a few seconds, I began to descend as well. Usually in order to speed up my travel even more I "sprint" or swim once I enter the elevator or escalator because I have both in this area.

 

But somehow after going down it a few seconds when I began the sprint/swim my character phased through the completely solid walls of the tube & fell out and died near the bottom of the cliff/mountain area we were trying to travel down from.

I don't believe it was me lagging and missing the entrance because I traveled down it a couple of blocks before it happened. I'm not sure what exact information I should also be providing, but if anyone has any ideas about what may have caused this or what additional information I need to provide, feel free to reach out.
