Readers and professional critics get a real kick out of bashing films with continuity lapses. There’s a rose in a vase at the beginning of a scene that turns into a carnation at the end of a scene. A man is wearing a red tie when he starts kissing the girl and a blue tie when the kiss ends.
Those are continuity issues. A script supervisor is supposed to maintain documentation about what’s in the scene and what’s said to ensure that in the flurry of camera takes and other changes, ties don’t change color and flowers don’t change their species.

Likewise in publishing, it was traditionally the job of a line editor to catch continuity lapses. Sue had green eyes in chapter one and blue eyes in chapter eight. Joe lives in a brick house in chapter three and a house with Vinyl siding in chapter fifteen.
Publishers are reducing the sizes of their staffs and may no longer have professional line editors, smaller publishers may rely on copyeditors and proofreaders and hope the author catches his/her continuity issues, and if you’re self-publishing, the buck stops at your desk.
Some authors create a dossier on each character before they begin writing: name, hair color, eye color, physical traits, habits, place of birth, typical expressions used, etc. Every time they refer to a character, they check the file. If you don’t do this–that is, you tend to make it up as you go–you can search your MS on the character’s name to see what you said about him/her earlier in the draft.
However, this becomes harder to do when you’re writing a novel that’s part of a series and have to laboriously search (if you can find them) the final manuscripts for prior books and/or search the Kindle editions for descriptions.
When I write, characters, houses, and other locations show up as needed. I’m not bothered about continuity at that point because the scenes are transient, meaning I don’t intend to use them again. But then, what if I do? I’ve spent the morning going through the Kindle editions of my Florida Folk Magic Series looking for the description of a so-called dogtrot house. At the time, I had no idea I’d write a subsequent novel that needed to have that house in it. Hell, I couldn’t remember what it looked like, so I had to find out what I said before.
I don’t have an answer for this problem. If you stop writing to record a bunch of info about a character/location/house, you can find it later. If you don’t stop, you’ll probably end up with a better scene because you won’t have interrupted it for “record-keeping.” While I’m writing a novel, I keep all kinds of notes on scraps of paper: but these get lost. I guess I need a better filing system.
