Also in the game folder, there's a file called archaelund.log that might contain useful information, we might ask you for it.
Finally, there's a Unity Engine system log called player.log. This file is the one we need if the game crashed for you; the tricky part is that it gets overwritten if you reopen the game. So before reopening, please send it to us or make a copy of it. The file is typically located at C:\Users\(your windows user) \AppData\LocalLow\4 Dimension Games\Archaelund\player.log . Its location depends on your Windows installation and user name, but it should be easy to find. A copy of the previous player.log file also exists, called player-prev.log is made, so if you just reopened the game once, data can still be saved.
