In https://en.wikipedia.org/w/index.php?diff=728973102 AWB caused a broken reference name. It removed all the reference info, and just kept the ref name.
I didn't have any real settigns turned on, just typo fixing, skip settings, gereal fixes, etc.
Computer and program info
Windows 10
AWB rev 12004 (not sure if this has been fixed since last official release)
