Yesterday I got to chapter 2. I have done the fist fight in Hairy Bear Inn with that fighter for the quest and as a reward for beating him I've picked the golden necklace.

The problem is that I had full inventory, so the necklace dropped on the floor. I saw it on the ground with the alt key but I was unable to pick up. Is there any way to get it, or I have to load earlier save? Also is this a common problem or I was just unlucky?

Thanks for all the answers.

Items on the floor will be removed when a new area loads.

I know, but that's not the point.
I have sold something to the waitress, yet I could not pick it up, as if it was not there.

Yeah, if like me you are the kind of guy that likes to loot everything in sight you're going to have a bit of a headache with inventory management in the Wicther ;)

Actually here in TW1 I have learned to be more picky about what items to pick (no pun intended). But at least the innkeepers are useful for storing.

Yeah , me too. It still bothers me a bit when i have to dispose of Blueberries or somehitng like that to make room for something else though ;)

I'm a hopeless hoarder i guess.
