Sometimes while playing, for example when I am in my house, suddenly, even though there are torches, the house becomes dark. I then break a torch and place it again - everything becomes normal again.
This has happened 3 times.

This happened to me when loading chunks (just moving trough the world). When the light source is in the edge of the chunk, the next chunk doesn't receive illumination.

Yes exactly... And sorry, I am new, so could you tell me how to reply to a specific comment?

Does this happen after you reload the world, or after you return from the Nether/End?
