No hole on mining level - intentional?

[analog owl]

Since I never actually played EA, I wanted to check in if this is something that can just happen or not. A few days into the game, I am unable to find a hole on mining level 1 after removing all stones and boxes/barrels.
I did find an ore vein on the floor, but no hole.

Is this just something that can happen and stops my mining progress for the day, or something worth reporting?

Thanks already for any answer! (:
Have a nice day!

at what floor the hole wont show up? the hole to the next floor should be showed up after you break some stones, doesnt have to break them all
also, the hole is usually hidden behind a wall so you might need to check it thoroughly
otherwise .. it may be a bug, if you happen to have a screenshot of it, you can report it on #1105382785826443264
