my main character is ordek, dwarf slayer, but images in this post are done with an alt (erok) to verify if it's an account problem or a character problem.
I was contacted in game by Tion, who asked me to explain my problem in game (now solved, conqueror helm disappeard) writing in chat advise.
I discovered that I can't write in chat advise.
Finding the thing strange Tion suggested me to make a post.
Some images to explain:
in chat i write /ad to pass in advise chat (or /advice)

and it works

but when I try to write

the result is the writing in the red box (it is in Italian, and means unknown command: / ad)

the chat advice is flagged in the general chat tab (the same on which obviously I'm also trying to write)

I hope I was clear and complete.
it did not cause me any particular problems and I did not even realize it until Tion asked me to write in that chat.
thank you for your work and support.
regards!
