BUT YOU"RE NOT MISSING ANYTHING!
You know that caps lock dont make you corect?
Yes you are.
In grymforge you long rest 3 times and Nere suffocates ... all Duergars leave and take Gnomes with them. Therefore you just lost whole Barcus Wroot questline.
In Goblin camp, if you kill all 3 leaders before you talk to Halsin he escapes by himself. (I wonder how he knew.) Therefore you just lost conversation.
If you run around Waukeen's Rest but dont do anything there (dont even look) and Long Rest ... Flaming fist leave, and that blpnde dude dies.
If you reach Githyanki patrol without Lae'zel and Long Rest befre fight, they kill her.
And many, many more.
And there are no indications that this can happen.
None of theese situation where you picked something, they all "just happens".
