Inaccessible area in The Caverns

Bug report: 4240762234

In "The Caverns", there is an area that cannot be reached. As you can see in the screenshot, the stairs lead to the next area (Ancient Pyramid).

The whole map is discovered (later on, I ran through from the start of the cavern). Also, there is a crafting recipe there.

This is a secret area with a hidden entrance. You can find the answer on this forum, on Google, or try to find it yourself.

Oh, I see, thank you!

I was looking for a lever or something, but I'll have to search better, I guess. :)
