For the past few weeks, the listing order of the guildhall transporters has been changing. There are only two of us in this guild, so we know that it isn't us making the changes. Also. the listing order of our houses on the guild amenity, which we don't even know how to change, are constantly reordering themselves. This can make for some interesting but unnecessary trips to the wrong house.
Same for me at least on the housing, I haven't noticed it on the portals yet. And yes I have gone to the wrong house a few times LOL
