Suspending note drastically reduces review count

Hi all,
I have noticed this behavior both with 2.1.46 and 2.1.47. While reviewing, sometimes a note appears (default basic type with front/back card) that I need to suspend, which I do with the default shortcut (!). Then, the review count in green drops drastically. I have noticed drops of 20 to - just today - 100 cards. I understand that a massively clozed note has a lot of siblings that should get suspended too but, again, this happens when I suspend default basic type notes with just front/back cards.
I wonder if anybody else has noticed this or I’m missing something, any ideas appreciated.

This is caused by buried siblings, and is resolved in the v3 scheduler.

Good to know, thank you!
