The Demo had two game breaking bugs.
Fleeing Enemies
I previously claimed that fleeing enemies was fixed, but it looks like I did not test very thoroughly. In the overworld, it would fail to load the terrain if you were too far away from your camp or the dock (if you had not yet found a camp). So I have updated the way flee works to compensate for this. Now, the game will keep track of your location and update the place you flee to every time you enter a new terrain tile. This way, when fleeing, you will return to the latest place where a new terrain tile was entered, instead of all the way to your camp.
I think there may still be some issue with this, so I will be looking more carefully at it later today.
Entering Cities at Night
I found the game would get frozen if you tried to enter a city at night. It was a simple mistake, and it is fixed now.
