So now with the new update if you are just wanting to play and didn't get into the FSW mess you still are in it
You see when I clicked to go in world was told not a FSW player tried again same message so if I am not playing FSW Jagex wants me to feel like I am some low life now need to pick a world I can play in like I guess some free to play player has to ergo am now a second class player not wanted????
sure feels that way
If you are not a FSW player, you can't even see the new worlds, let alone being able to enter it. I don't know how you get the message you mentioned.
Anyway, you can always manually select a world, and perhaps even better just FAVORITE some worlds so you can just click those worlds to select exactly the world you like to enter.
I get the same issue on mobile and desktop. I don't have a FSW account. How hard can it be for the game to check the account type before auto-selecting a world? You don't expect a free player to be auto-logged into a members world do you?
