Hello

Found this:
https://github.com/TrinityCore/TrinityCoreCustomChanges/blob/3.3.5-1vs1/src/server/scripts/Custom/npc_arena1v1.cpp
https://github.com/TrinityCore/TrinityCoreCustomChanges/blob/3.3.5-1vs1/src/server/scripts/Custom/npc_arena1v1.h

Downloaded the diff from here:
https://github.com/TrinityCore/TrinityCoreCustomChanges/wiki

Got latest TC Rev cloned. and i did "Git apply 1v1arena.diff --reject"
All good. CMake and then Compiled it. No problems.
Spawned the NPC in-game.
Menu works and to create a team works.
It signs up for Arena. But no announce in chat like it supposed todo.
Not working. Even with lots of players in queue at same time both rated and unrated.

Cant find any problems.
Anyone else who can?

THanks in advance
