Crashes with undefined method `children' for nil:NilClass when saving file

[badosu]

Describe the bug
Sometimes when saving a file solargraph shuts down, I have autoformat with rubocop and diagnostics enabled.

Find stacktraces and log context here

To Reproduce
Unclear, I haven't been able to extract a minimal repro from the commercial project I work on.

Expected behavior
To not crash

Debug log

I can't share most of the output but this feels relevant (and generic enough):
