Problem with converting merged epub to mobi

I know Calibre is having some problems with the epub to mobi conversions.

I rolled back to 3.45 and noticed that epubs that have been merged are throwing the error

Spoiler:

calibre, version 3.45.0 (win32, embedded-python: True)
Conversion error: Failed: Convert book 1 of 1 (For You)
