It is no longer possible for clients to connect to a server without tellme. This mod used to work serverside, and the as an admin I would add it to my client to easily use the commands. Now I can't add it to the server, because all clients need it.

Oh yeah this was reported at one point but I had completely forgotten about it already... I think some command stuff changed between one of the semi-recent MC versions that "broke" this. Which MC version are you in?

oh yes sorry. 1.19.2. Built tellme from current source.
