Guild Wars 2

For my account, all toons, the merchant and TP recognize only what is in the start backpack and not the additional bags. What is in the other inventory bags seems to be “invisible” to them.

are any of the bags invisible bags/safe boxes/pact equipment box? items in those kinds of bags can’t be sold to vendors or on the TP

No I’m running 18 slot boxes. What is in the “starter backpack” is seen by the system. Otherwise not. Also the deposit all collectables function behaves the same way.

that’s really odd. maybe you should try making a support ticket, see if they can figure out what’s going on.

Invisible bags/boxes come in all sizes, not just 18 slots.

Here are some examples (bottom of page): http://wiki.guildwars2.com/wiki/8_Slot_Invisible_Bag

There are other bags/boxes with the ‘invisible’ feature, as well.
