I have this file in original distribution package. :) I just want to improve your quality by reporting this issue.
The new theme version on themeforest that we have released yesterday have fixed this issue.
I don't see any updates in my Wordpress console (or in Insight Core - Updates).
Does it mean that no automatic updates supported, and only one way to update is downloading from Themeforest site?
You can use manual update method by download new theme package on themeforest to update your system.
We are sorry for this inconvenience.
