This happened to me (again) just last night... 🙄
I was having a great session with a crew, 1 of which was new to the SoT. Anyways, he discovered the wonderfully funny text descriptions of just about everything in the game in the menus.
So, he asked me to read them aloud to him, since I had the most cosmetics - this was a wholly unique and new experience in SoT, even for me.
Sadly, because I had so many cosmetics, I spent more than 10 minutes in the same menu, got Lazybearded, and couldn't reconnect to my crew because I hadn't learned their exact gamertags, and the recent players list hadn't updated yet for some weird reason, leaving me completely unable to reconnect.
My crewmate never got to finish hearing all of the funny descriptions simply because the game thought that I had stopped playing when nothing was further from the truth - we were just playing our own way in the sandbox. Why should we get punished for that, especially when we're still active (even if it is only in the menus)?
