I can't seem to quick save my game, I checked the keyboard options and I'm hitting the right buttons, but the keys are not responding. Is there a workaround or a fix for this?

Quicksave is actually working, but only one quicksave slot is available, you have to manually load this slot from the game menu, because quickload is NOT working (I mean pressing SHIFT+l does nothing).

Seems to be the same problem with the inventory button. The manual says to use 'i' but it doesn't have anywhere to define it in the game. Just clicking on your character works though.

I had this problem at the beginning but then I noticed that the buttons for Quick Load and Quick Save were capital letters, so if you want to do a Quick Save make sure you are hitting the "S" key and not the "s".
Hope this was helpful!

2024 and this crap STILL isn't fixed. Super irritating.
