Something changed in this update that alters the way slots are displayed in the Guild Bank.

instead of ordering like the default guild bank:

[01][08]
[02][09]
[03][10]
[04][11]
[05][12]
[06][13]
[07][14]

it now orders like this:

[01][02][03][04][05][06][07]
[08][09][10][11][12][13][14]

I've verified that the contents of my Guild Bank have not been rearranged.

I realized that the newer method allows for adjusting the # of columns that are displayed.. however, it makes it very difficult to keep items in the guild bank organized in a way that is compatible with the default layout.

For now, I've just set the # of columns to 7. It gives me a tall guild bank window and the only big difference is that the layout is rotated -- http://i.imgur.com/L9Dvx.png

Perhaps a toggle option would help for this?

Fixed on upcoming version,
