Thank you Maniakaal for helping us understand.
I am playing on an iPad, which probably makes it the mobile version.
If the maps are configured by browser, then that's just as an important bit of information to share as the coordinates are.
I did go back and look for -154 66 without success. Because my own coordinates were positive, I didn't realise that 4 quadrants were being used.
Does this mean that the Clan search function only returns values that match by browser?
Can you confirm that cross-browser clans are not possible?
I will have to seek another clan to join, sorry Primus.
At least we learnt something in the process.
It is what it is.
Good luck and have fun.
