Gagdet cycling is broken: if you want to go to the third explosive using the keyboard shortcut (default 3), mashing it makes you cycle through each explosive (pull it out, put it away, repeat for the next explosive), whereas you can go straight to the third explosive using mousewheel. It wasn't like this until the pre-launch patch. Also it makes picking things off the ground annoying too because you have to pull it out and then put it back, unless you fling the mousewheel back to the thing you wanted equipped, whereas before if I wanted to keep my primary out but pickup something like an RPG I could just mash 1 while picking it up to 'pull out my primary' again.
Holding a throwable gadget and then opening the comms menu still causes the gadget to be thrown the moment the comms menu is pulled up.
Edit: Also hitting "reset to defaults" on the key binds applies the default key binds instantly. If you accidentally click it (or if i wanted to see what the default was but not actually use default binds such as in this post for selecting explosives), then you cannot undo it or have a prompt to confirm the reset.
