Here is short history about what happened; Few days ago I noticed there is a big red box that has question mark on it on my Velothi Reveire house. I asked for help from ZOS developers. They were helpful enough to suggest I should uninstall all addons, repair the game and try again, which I did. Until they asked me to uninstall/re-install the game to try it out. If not, I can make a post on forums about it.

Since I am in no position to download GBs of patches just to try if some random box will disappear from my map, I am creating this post to get it done or see if anyone else experienced the same issue (or has some solutions for it) Oh right, after I asked help from my guild, someone said he also has the same bug for last a year and the box is still there, he couldn't get rid of it. (On same house)

Here is some info that can be useful in some way;

1) Basically it is giant box on Velothi house. Which seems to be also recognizing itself as a 2nd Velothi house aswell
2) Yet it puts a cost charge there like it is a wayshrine. When I click it via gold, nothing happens.
3) I can safely go in and out of the house.
4) The visual bug seems to be only on my main character. Box is not there on my alts.
5) I am %100 sure none of addons are cousing it since I uninstalled them all and repaired the game without them.
6) I own the game via steam
7) No I don't want to uninstall and install the game if you have some better things to suggest, unless it's my last chance.
