Permanent sacks and sack stacking

[Farwalker]

Here's another sack related bug.

It's possible to get a permanent sack on the ground if it lands on, for example, the spot where you emerge from the caves N of the Farrock Monolith. Not sure if this applies to other similar locations. You can close an empty sack in this location and it won't disappear.

You can also end up stacking sacks on top of each other in that location, not sure if it's the new sack or the old sack you retain access to, but it still works as a permanent sack after that as well.

Thanks
