ok, I have a server with 3 overworld worlds, 1 lobby and 2 other overworld worlds...
in world lobby worldborder works, but in the other ones the border is set at size 2048 but when doing /worldborder get it says the size is 1000000... so I don't understand why is that... I tried using /execute in [world] run worldborder set 1000000 but it doesn't work, even after restarting...
