Atlas Frozen

I'm in a private league with 2 friends and we or sorta just doing a ssf group play thing. So I got all the corners of my atlas explored in white tiers had 4 watch stones and I was like ok ill socket these into this area and just start running some red maps that I had saved up from Zana. Put the watch stones in and ran the red maps I had. Well Al-Hezmin showed up and I had no clue the guy was gonna run off with my watch stones. So now i'm stuck on white maps because i have no stones to progress. Wouldn't be a big deal if I was on trade league but i'm not so i'm pretty much stuck. Why would you even allow something like this to be in the game and not explain it at all.
