Another instance of same issue:

Issue created from fantomas-ui

The sample here is a bit extreme as I used 20 for page width, but I was able to reproduce same behaviour with more representative production code.
The result of formatting issues an indentation warning, as 3 starts in same column as with keyword
There exists a valid syntax for those settings, where with follows with a line break (see Expected section)

Code

type A =
  { Number : int }

let a = { Number = 2 }

let b = 
  { a with Number = 3 }

Result

type A =
  { Number: int }

let a =
  { Number = 2 }

let b =
  { a with Number =
      3 }

Expected

type A =
  { Number: int }

let a =
  { Number = 2 }

let b =
  { a with 
      Number = 3 }

I get this warning quite often too. It would be really nice to have this patched.

Warnings are usually something that should be taken seriously (like non-exhaustive pattern matching). It would be nice to have warnings be a blocker on PRs / give error on CI builds.

Imo the suggested formatting looks much better too 😄

Not a problem anymore.
