There are really lots of bugs in the windows version. I will try to describe some of them:
1. Since yesterday I can not access the general tab of the battle reports. As soon as I try to open the battle reports, the game hangs and does not recover. Other tabs ("Battleground/Stoneheart trials", "Undead/Corrupted") can be opened via the short message on top of the screen. But without the general battle reports the game is hardly playable.
2. Bug reports can not be submitted ingame. If I try to acces "Settings" -> "Guide" -> "Contact us" the game hangs and does not recover.
3. Hamlet owners are often shown with wrong avatars. The name is correct but avatar including alliance, coalition and level are completely random. This may lead to serious trouble if you attack the wrong guy because you rely on the information shown in the hamlet overview.
4. When the game is loading is displays a message about a new version beeing available. The message has 2 buttons: "OK" and "Cancel", Hitting OK is not updating the game client.
5. When you try to return a fleet immediatly by using a time boost exceeding the current return time, the time boost can not be applied.
6. The screen labled "Quests" in the "Eagle's Nest" has no contents.
7. Items in the temporary inventory sometimes are display with the wrong image.
