File version problems

[nd5y]

I'm getting this when trying to replace a file with a new version:
Internal error
[Xe8RhsqkcBMd3m9wwl@JoAAAABQ] 2019-12-10 03:31:18: Fatal exception of type "MediaWiki\Revision\IncompleteRevisionException"

Try saving the file with a different name. Seems like we've had problems with versioning of files in the past.
