Hi David,
I am using builder for windows but when recording it seems does not recording mouseoverelement event. This cause subsequent popup clickelement failed during playback.
I used:

Selenium builder 3.1.3
2)FF 54
3)geckodriver 0.19
4)selenium server 3.4.0
Thrown log:

Selenium buillder 3.1.2 i tested it just now is working well. I am wondering why mouseOverCommand support was removed in 3.1.3. Shouldn't it be backward compatible?
My working setup:
builder 3.1.2
geckodriver 0.19
selenium standalone server 2.52.0
FF 40
