Guild Wars 2

As just said, I couldn’t get a reward for Tequatl defeat from reward chest. Also, i received carma chests that prove that i defeated him.
Bug report is sent and I require its investigation.

There is only one large reward chest per character per day, so this is likely the second time you did it on that character. You still get the small chests that pop up on the lower right of screen on your second and third times (and likely more, I have never done TEQ more than 3/day), just not the large chest.
