Dig up a rare shard quest never completes. I have built the shard mine and gotten 3 rare shards from it, but haven't been asked to turn in the quest yet. See the boxed areas in this screenshot:

The special abilities of the Human Ranger has got the discription: "undefined" (esp. Magic Arrow)

Mission "Lillith Dessert Ruins" is broken. After the final battle you can't open the chest. After refreshing the browser you can open the chest but there is not a tresure inside. And the quest doesn't end. You have to go to town. The quest seems to be finished cause Lilith got their new equipment. But there is no Level Reward.

Mission "Jareq's night in the dessert" is broken, too. You should go back to camp and nothing happen. After refreshing browser and go back to town the questlog is gone and Jareq's new equip is there. But no quest reward and so on...

I started a MP game. It is in the loop interacting. I have refreshed twice. Any suggestions on how to get out of it? I can't use chat or anything else in the game.

When I started fighting the bandits' leader, things started to disappear (trees, one of my companions, one bandit, more decor and the bandits' leader's health bar), and, after that, I wasn't able to fight

Unsolved missions have a grey picture in the background (thats okay) but there is the same test on every picture: "Complete "The marauder camp" Mission to unlock!" (not so good^^)

Game freezes if you leave the fishing zone. Refresh solves the problem.

12 "Raider Pouch" still in inventury after completing the quest.

Golden (Second) chest empty in mission "The road to Quevira".
