Alright thanks for the info and for your efforts. But there is not any working solution as of now, correct?
I am just wondering why would this file be added if it doesn't do anything besides killing autocompletion? On page1, you recommened to delete it (I haven't tested that yet because I wanted to keep my install folder clean. But I'll have to make a save and do it soon if nothing else can be done).
I should add that I am new to ST3 and so far it's feeling great. I'd love to see this getting fixed though
