Killed Volrath earlier in the week and got a strongbox, but I've killed him pretty much every day since then and have gotten nothing, not even Conq. Is this a glitch or something? I've always at least tagged him.
Unless that is a non-documented "hotfix", that's not true. Both the box and the daily (last week, at least) conquest were just that - daily. I got 350 (and the box) from Tremblade monday, tuesday, and thu last week, capping me on Conquest before i even realized it.
I will say, though, that i didnt get them the first few times i killed her on wednesday, even though i was on her the entire time. It's buggy... like everything else in Trashcan.
