I received the "You can't carry that here." When moving grass bundle from cart to resource collection slot (back) today on login. I had opened the cart inventory and attempted to pickup where I left off last night grinding out thread. When I dragged the bundle of 4 grass from the cart inventory to my resource collection slot (back slot not bag) the interface responded "You can't carry that here". I dropped the grass on the ground and then picked it up which worked as intended and put the grass in the collector slot. I then tested by placing the grass back in the cart, followed by moving the grass from the cart to my collection slot. The message did not appear again. I attempted to reproduce the issue by logging out, back in and conducting the same task. The issue did not represent itself.
