After downpatching, my game does not allow me to select dialogue with my use key F, it makes me press ENTER instead.

Additonally, it does not allow me to skip the end-chapter stats screen with F.

In my Config and settings, only my F is bound to 'use/sheath weapons'.

If anyone can help, please do comment!

That is because 1.4 is the patch that allowed you to use F to do that.

So you'll just have to live with it, or not use the downpatch. (or use some software to rebind F to enter if you must)

Ok, I thought that was it.

I just need to practice using enter instead then. :P
