There's nothing around the spot I'm supposed to be, so I'm kind of... confused ?
I'm turning around since hours now so I hope someone know what's happening... xD
Thank you <3

click on the blue word on your lvl 18 quest ant it should lead you to your destination.

Thanks you for your answer ! <3 I did that many times already and it lead me at the same exact point xD

Meanwhile, I did some other quest I had to and the lvl 18 one disappeared so... I guess it was just an issue from the game ? I hope I didn't missed something important. xD

If you see the quest has a 6400 number, I think you must reach that amount of cosmos (you have 6208)

Oh, you're right ! I was confused about this number too. Thanks for your advice :D
Some quest are really confusing for me because everything in the description are chinese characters. xD
