Yes, as I had mentioned, the overflow idea still works (tested and unchanged). But, if you go WAY over weighted, you can be totally stopped from moving. This happened to me when I first started playing, and I had found the elm boxes on my recipe list. I was "Wow! So many slots! I'm going to fill up my whole inventory with them!" So, I stood there crafting them, and filled up my whole inventory, and then I was going to go party, and realized, "Hey! I can't move! At all!". So, I had to destroy a couple so I could move again. It takes a lot of weight to lose all movement, but it does happen. Like maybe 10 times over weight or so. Maybe less.
