I started using the loot filter but after a while I started to see that my backpack was not filling anymore.
I didn’t even realize it, so I went to see that the items didn’t show up anymore. When I opened the chests I could see them on the floor but there was no way to get them.
I turned the loot filter on and off and continued the same thing.
You would not be the first person thinking it is a bug
Just try to watch the chat, you actually get feedback if you press any of the toggle buttons (Loot Filter and Item Labels)
Press the key and keep it pressed. That’s an error I made at the beginning, I thought it was press to enable and press to disable, but you have to keep the key pressed.
