..... A guildie decided last night to start making the blue 28 slot bag for us (his guildies) and when he got to me has asked if I needed all 5 bags.
All 5 bags you say? - but, but I only have 4 bags and the initial backpack - so I can only use 4 ... right?
Wrong - you can take your starting back pack off and replace it for a larger bag.
/Facepalm for playing for 3 months and not realizing that.
