Patch Notes: The Materials Bag and the guild overhaul

The Materials Bag

Online, every General Store now sells a Materials Bag for about 500 gold. It holds 300 kg of crafting materials.
On the enhanced inventory the bag opens beside your pack, like the cart. If nothing else is open beside your pack, use the Materials Bag button at the bottom of your pack. On the classic inventory, reach your bag from the Stores page.
Anything you gather goes into your bag first, then your pack. With no bag, it all goes into your pack. Anything that doesn't fit is left where you gathered it, and the game tells you what was left.
Your Stores are now kept in town. In any town, open the Stores page (on the pause menu's Holdings tab) to put materials in (one material at a time, or Put everything in) or take them out into your bag or pack.
Empty your bag into your pack from the Stores page, anywhere.
Crafting stations use what you carry, including what's in your wagon. If your Stores are short, the rest is moved in from your bag and pack. Goods bought with gold on the market are never moved in.
You can't sell or drop the bag while it has anything in it, and it can't be traded.
Food in the bag spoils, just like food in your pack.

The Guild tab is now split into pages: Overview, Members, Treasury, Vault, Arms and Settings, and Stores where professions are on.
Rename your guild: the guildmaster can change the guild's name or tag for 25,000 gold. The gold comes from the treasury, from gold your members' online characters put in. Renames are limited to one every two weeks. You can't rename in a week your guild is in a siege or a Tourney. Your guild's past entries in the Chronicle keep its arms.
The guild vault: 50 item slots, or 100 if your guild has bought a hall. Put items in and take them out in any town. By default, officers can take items out 10 times a day, and members and recruits can put items in. The guildmaster can grant or revoke each member's access and set their daily limit. The chest in your guild hall now opens the vault.
Richer arms: 16 new devices (40 in all), 7 ways to split the field into two colours, and a colour of its own for the device. Pick them from pictures on the Arms page. Guild banners, shields and tags all show them.
Players who haven't reloaded the game since this update see no arms for a guild that uses a new device, and see split fields as plain.
Guild names and tags now go through the name filter, and a refused name says which word was refused. Names with numbers in them, like "The 22 Blades", are allowed.
