Some players managed to launch an upcoming riot-map and place intriguing screenshots. It would seem to be a normal practice when data miners find secret information in the game files and publish it. If the patch is on the OTW, then it is no longer so secret and internal. This cannot be considered a leak and removed. And where you can not delete - ask to delete.
Nobody leaks - the players themselves found the card in the files and launched it. Okay? The position of LO on this issue is not clear to me. In addition, RIOT has already been officially presented and will appear in the coming month. The mode is already ready, except for small details. What the players found in the files is, in fact, the final product, not the alpha-prototype. Why is it removed? Tell us. Even personally, my comment with a screenshot was deleted here yesterday on the forum.
