Installing Sublimerge Pro (in ~/.sublimious) fatally borks with sublimious

Tried it twice form a clean install.
First time I added Sublimerge Pro after sublimious was setup with a few extras, and I lost the 'space' menu keybinding.
Did a clean config reset.
Tried again adding Sublimerge Pro as the first add-on. It worked once, then, after restarting the sublimious space menu keybinding was gone.
In each case, after this happens, editing the ~/.sublimious file and restarting sublime does nothing.
Had to purge ~/Library/Application Support/Sublime Text 3 and start over each time.

Can't define 'borks' an more than what I experienced. I'm a noob sublime user so I don't know what other specific info to post.
In any case, it's easily repeatable.
