I literally can’t post a crafted item in any chat channel without the link being broken and not being posted at all. Also it cuts off the entire message after the link.
Is this just a problem with my client or have others this issue too? Also, if it is a bigger issue, can customer support perhaps give some intel on when this can be expected to be fixed?
The whole itemstring which gets converted into the clickable link (and is far longer than what you see as text) is probably quite long up to the character-limits of a chat message.
Once you reach that limit you cannot type anything else into that message.
