Lichess "add a new chapter", today, started to add chapters to the "top" rather to the bottom.

Try simply creating a study, and adding a chapter called c1 and then a chapter called c2, you will see chapter 1 is called "c2".

It's neither good or bad, I just need to adjust my current studies and manually drag the next 10 or so chapters until I reach 64 to the position it's ordered in the bottom, yesterday and always it added them to the bottom automatically.
I'm manually dragging for now the yet not completed (less than 64 chapters) studies to be ordered. Next study, I imagine I'm not going to manually adjust them, so the chapter 1 will be the most recent one, rather than the oldest one. Is this desirable? Why did they changed it to be like that? I imagine people create studies more in the order than they are going to be consulted, that is, chapter 1, then 2, then 3...

BTW, this is NOT a big deal, it's ok if it remains like this, I'll adjust. But I'm warning in case it was unintentional behaviour.

For example this study lichess.org/study/l3dOT9s2, look, the exercise I just added, in order of numbers, are all messed up. Sometimes it adds them after the last added chapter, sometimes to the very top. It's a bigger annoyance than it seemed.

I noticed this yesterday too and it's really annoying. I hope this was an unintentional change that can be reverted.

I'm seeing it too. Does anyone know which repo to raise the issue at?
