Not following the format since this one is pretty self-explanatory from the title. Unfortunate it's quite intermittent but I just noticed it today after upgrading to the preview patch (and then downgrading thinking that was the cause). Tried moving the "Endless Space 2" folder in my documents and verifying integrity. Tried with CrossFire on/off. 


Reproducibiliy: Good Luck.
