Consequently, wonder if they aren't all related.

I will try going back further. You might be right because this is a new problems. Calibre hasn't really rolled out new changes enough to warrant upgrading so it's not really a step down to do it.

I'll just go back one at a time to find the last best update before the problems and report back.

The initial problem I had was straight up Calibre not converting the epub to mobi files for some books regardless of them being merged. Once I rolled back to 3.45.0 the only books having problems are the ones that have been merged.

So, I guess I will have to play around to find out when both work. Isn't too far back though.

Update:

I installed the latest version of Calibre that supposedly fixed the problems, but the epub merge still threw that error.

I uninstalled and downgraded to 44.0 and it works fine.
