"You can't put non-empty bags in other bags."
For three years, I've been treating this as a basic axiom of World of Warcraft (along with "don't stand in the fire" and "never start a land war in Stranglethorn Vale"), meaning that every time any of my characters wanted to replace an old bag with a larger one, I'd do the following:
- Painstakingly determine which of the spaces in OneBag or All In One Bags corresponded to which bag slot
- Empty out the bag I wished to replace (selling or banking items if I didn't have room otherwise)
- Place the "old" bag inside another bag
- Plunk the new bag in the now-empty bag slot
If you've been following the above procedure like I have, you can guess that swapping out an 18-slot bag for a 20-slot bag when your bags are mostly full is no fun.
So you can imagine my surprise and amazement when one of my guildies told me that you don't actually have to empty a bag before replacing it at all! Just take your new bag and drag it over top of the bag you wish to replace. Voila, you're done!
Do I feel silly? Well, yes.
Am I hopeful this will help some other nub out there like me? Absolutely.
