On the page of hunting you can choose to reroll the currently available quests for 1k, 2k, 3k, 4k and 5k pebbles daily, but there's also a text saying that they will reroll for free at midnight. I've been paying close attention to this the past couple weeks, and I've noticed that they actually do not reroll at all. Each morning I wake up to exactly the same quests I had available before I went to bed. (And yes, the game's midnight happens while I am asleep at 1am in the morning for my current timezone).

Initially I thought it might've been bad luck cause I only had a few hunts to chose from, but by now I'm lv38 and have quite a few quests available to me, so I no longer think it is just bad luck that I reroll the same quests I already had. They simply aren't rerolling at all.

Now if I may also insert a mini suggestion to this; I would love it if the daily free reroll had to be done manually. Basically the first reroll of the day is free but has to be manually done, and after that the prices increases with 1k up to the maximum amount of rerolls. The reason for this suggestion is that sometimes I am able to do a quest with a high or even 100% success rate, but I need to wait for the companion cooldowns to be up to swap some around to get the right synergy combo. If the wait for the companion cooldown (which is something the game forces me to do and not something I do by choice) happens to go past the midnight mark and the quest disappeared automatically, I'd be pretty miffed. Especially for the higher level quests that don't show up that often and require very specific combinations.

I can also confirm this using the Wild Wolf hunt as an example. If I have 50 KB and complete a hunt or reroll, I get the WW hunt. That hunt then does not go away at all until I stop having 50 KB and reroll manually, even after reset or even multiple resets. If it was rerolling properly at reset, that hunt would not be there anymore because I wouldn't have 50 KB anymore since I list them on the FM almost immediately. It's actually very, very annoying that I have to pay to stop it from taking up a slot when I have 0 intention of ever doing it.

Oh yes, true. That definitely makes it 100% certain it isn't rerolling because I've had that happen too!

It is another point I'm kind of miffed about as well. I'm currently constantly staring at a big red 2 in my notifications because I listed my KBT on the FM because I do not want to do the hunt (yet), but it keeps showing up if you have the right items for it. The FM listings have expired by now, but the big red 2 won't go away unless I claim the items, but then the hunt would show up and waste a precious slot. Very annoying! I do have a separate suggestion for that though. I came back to add that to this post. Because ideally, all hunts you have unlocked are available to you to choose from, but the amount of hunts you can go on is determined by your level (that would idieally unlock a few slots every so often) and the amount of slots you have purchased (ideally with pebbles). It would make rerolling quests completely obsolete though and the devs would have to think of a different way to give hunting a pebble sink. But with how many hunt are downright impossible to get a decent success rate on because of the required synergies, it feels like a very desirable change to make. I'll link the suggestion here so that any discussion regarding that suggestion can be kept to the suggestions forum: Forum - [Professions] Balancing and improvements (lorwolf.com)

If this is a bug, I also can confirm. I hate doing the level 3 quest that you can't get a 100 on with anything, so almost never do it. I also sit on higher leveled treasure and they never seem to go away.

Thank you for the report. The Bug Index has been updated to include this issue.
