Error "You cannot do this yet!"

[Petervpg]

So i tried to look and I saw a lot of other people had the same problem... the problem is when i type example: /npc cmdadd -c -i -l shop
it says its added with no problems but whenever I right/left click it says "You cannot do this yet!"
Can anybody help me with this?

I'm noticing the same issue when the command fails to execute. I'm guessing you don't get the You cannot do this yet! message on the first attempt, but the subsequent attempts.

The console usually provides an error if something went wrong with the command, but a blank result from the NPC usually means that something went wrong. Me personally is struggling with longer tellRaw commands that are perfectly fine, but won't execute due to it's length.
