The Console is flooded and spamed with lots of server Notes.
This appears never after creating a fresh world.

Only when rejoining or by activating cheats. It starts random not reproducable. Sometimes it's the second login into the realms world, sometime it starts at the fifth time. Absolutly random.

It appears by using several marketplace mods like DINOSAURS / Camo Hide and Seek / Advanced Creepers and so on.

The server notes are:
