Seriously... My bag is almost empty but it does't let me to put things in it. When I craft, it drops stuff on the floor, saying that I can't carry anymore, though I don't carry that much!
Has nothing to do with your bag but with the wight of your items and the strength of your char, if you carry to much wight and your strength isnt high enough it will be dropped
My char has 20 strength, and the items in the bag only weight a total of a few hundred units. Before today, I was able to carry a lot of stuff in the bag, today it changed. Maybe devs did something that bugged the bag?
I have noticed that in my bag, I can't put any items in the upper slots. I had the bag mostly empty, and purchased something. It placed it halfway down the bag even though the top of the bag was empty. Could this be related?
I've had problem with the bag as well. I can put three items into it one after the other starting from the upper left corner going left, then I can't put anything in the forth slot, but I can put more items randomly into the bag.
