I’m not sure if it’s a bug or the devs just had another great idea, but I noticed legendary chests (and only those) disappear from dungeons if you do the same dungeon over and over.
Let me say this before: I always let at least 6 hours pass between each visit to a dungeon.
First time it happened in the Arena.
I did it once, twice, thrice … not sure about fourth time and then EVERY TIME I went there after that, the chest was simply not there.
Now the same happened to the Silver Mine: I did it once, twice, thrice … and then they disappeared. This time they disappeared in front of my eyes, while I was approaching the Scorpion Queen.
I even went out of the mine and enetered it again, but chests just weren’t there anymore.
Can someone confirm ?
