My character sold some iron stocks, and fortunately the player that bought it was a serious roleplayer.
The name of the secret guild where he is appears on the iron description below its name.
This is a potential exploit to be used by bad roleplayers...
Guess he will have to stay clear from crafting or craft only for himself until this problem is solved.

That is not the only place secret guild names are displayed to everyone Sad
In another area it displayes every player and every guild secret or not. This is something that should be fixed very SOON, not to be confused with soon(tm)
Hope this won't spoil the roleplaying part of PS. Another even more powerful exploit...
