Objects disappear from the viewport but exist in Outliner

Hello folks,

I ran into this quite a few times already. After hiding unselected with “Shift+h” and working on one current object, the other objects do not appear after hitting “Alt+h”. They still exist in Outliner, but I can’t get to them. Is that a bug or I just hitted some hotkeys accidently?

You’re in local viewmode which isolates selected from everything else. It’s indicated at the top left corner. Numpad_/ to toggle.

Gooosh, thank you!
