Edit: I noticed JEvents actually is updated, despite the error.

Mine too. My Edit Events/Create an event page is no longer tabbed. The titles of the tabs are there but don't work when clicked. The date entry is at the bottom of the "common" page.

This is after updating.

Fortunately, I always run a backup before updating, so I have reinstalled the backup.

Sorry - can you try this build please

We were creating a new index on a db column before we had changed its length

I'm still getting an error when installing, though the component version in extensions overview indicates the latest version is installed.
The extension updater tells me there's an update available for 3.6.45, and that 3.6.43 is the current version.
