[2020] In-game Interface disappeared (Sometime)

Originally posted by DougJunior: I have the same problem, every game 1 of my units the interfaces bugs out.
I can work with the 3 other guys normal, but 1 get stuck, i cant use moving or somethink.
Sometimes when you bash the button for 1 or 2 they do somethink, but 95% you can only let the guy stay skip his turn.

Please tell us, after installing the day 1 patch, this problem was solved?
