Mirroring features creates new bodies ONLY AFTER ADJUSTING UNRELATED SKETCH

This is just the latest in a litany of small annoyances that make me hate using Fusion. 

I had a design where I needed to adjust the first sketch by a few mms in 2 axes. This ofc (because it's Fusion) made it not fully defined and gave no indication why. Doesn't matter. 

I had a series of features mirrored, and then bodies mirrored and copied for slight changes and 3D printing. All of a sudden, one of the mirrorings decided it wants to be new bodies instead of joining and none ofc now none of the other bodies reflect these features. How do I get it back the way it was? (Combining the bodies then creates more problems).

Update: actually, I cannot even combine the bodies. It says combined but they do not add to the main body.

Nvm, I figured it out. 

The mirror plane I had offset from one face was now projecting the features minisculely offset from the opposing face. Creating a midpoint plane fixed the issue. 

...still annoying
