Is it repeatable? Yes.

Known Fix Don't ask for help. At least not "/help 3"

 

[Sorbe]

Note, "/help 7" will cause the the client to disconnect with an in-game exception screen, but not crash.

 

[UnionCraft]

We probably need a update to chatflow on the client, it has apparently been fixed in a newer version

[Darkosto]

Fixed in 2.5.5, this will be out in the next couple of days. I'm finished the last few tweaks.
