Item hotkeys change when holstered/unholstered

Is there any way to fix this?

I have my Halligan bar set to c in my inventory, yet when unholstered only maybe 1 in 3 times is it “c”. Perhaps of note, it isn’t yellow, I’m not sure why.

While that is a bit annoying, what I find FAR more annoying is that the hotkey I assign to my atomic lamp sometimes gets dropped when I holster/unholster OTHER things.

There’s a bug in there somewhere…
