Hi all,

I'd like to reach out to the community for help with reproducing the "0 Trophy Bug" for one of our Engineers to examine. If you are not familiar with the issue, please see more information here.

If you encounter this bug, please immediately send me a PM and include the following information:

Your User ID (found in the Settings menu, but don't post this information publicly. PM only.)
The Dungeon name and Guild name of your opponent
An approximate time of occurrence.

Also, feel free to use this thread if you have any questions regarding this issue.

Thank you very much!

I think I’ve mentioned this before, but just in case...I’ve only seen this once myself (but heard several others). It didn’t seem to be a cheater. One thing I noticed is that it didn’t actually seem to have anything to do with the person having zero trophies - when I attacked they had trophies (I normally check to avoid attacking newbies), and when they revenged me they had a couple of thousand (not likely enough time to gain so many). So I suspect it showing zero trophies is a side-effect, just as showing zero gold/stone is a side effect. I’ve attacked zero trophy people without having a problem a couple of times.

My best guess is that there’s a null value being returned due to a fault somewhere in the process of storing or retrieving the raid. Perhaps due to the account being locked at that time, as the person logs in, another person simultaneously attacking/revenging them, or something like that. It returns or stores a blanked/nulled person (not raid - the spell/etc. info is there so the raid itself seems okay), so without the person to store in the raid it shows zero trophies/gold/stone (because the blank person has none to take).

Less likely, the person on the other end is cheating and has modified values that are crapping out the db somehow.

Just some thoughts... it may be related to zero trophy people, it just doesn’t seem like it in my experience.

Just a note, saw someone post a screen shot the other day where they attacked a player, won, same player came up for them just a few minutes later, and hit zero trophy bug defeating them again. Same name - and the target player was around 10k trophies so very unlikely a clone the second time (though cloning I suppose could be an issue).

I’ve noticed (forever) that matching frequently throws the same person at you exactly twice within a few nexts. Not sure if they then go to the back of the queue, but won’t see them for hours, if not days. Wondering if it’s possible that someone is attacked, defeated, should be in cave-in, but gets served up a second time due to this fluke. That is, when I next someone they shouldn’t come up again right away, but they often do - maybe this problem has spread to include people in cave-in for some reason. Then when the second raid goes to be stored, it finds the player in cave-in and throws a fault, resulting in a null player being returned and all the zeros.

Not likely related of course, but just a thought, after seeing that the second attack pulling the bug when the first on the same target was totally fine. Doesn’t seem like the target player as such is a problem.
