I never had issues with auto space either. I use three languages with mine, and I like it. The only thing I don't like is that it adds extra characters on the keyboard depending on the language enabled, making all of the letters smaller. Annoyingly, it doesn't happen with German (I have to long-press regular characters to go to special ones), but it slaps the Slavic characters on the keyboard itself.
I installed Flow btw, like it so far. Swiping to the left across the keyboard doesn't delete the last word anymore, though

I honestly can't believe how much I've gotten used to that.
