Some bugs I have noticed.

If you build a city up to an already built resource the city builds it again, if you cancel this the resource is unbuilt.

Casting shrink screws the battle.  When the target dies you get two death scenes, one small and one big.  You are then left with the target as the current unit and the only way to finish the fight is to hit auto.

The flamewave spell does not appear to do any damage.

Cloak of the stars quest.  Vatula's dragonslayer has "no effect" on the quest dragon or any other dragon.  The dagon gave no xp for the fight.  I did not gain the cloak. I did have the shrink bug during this fight.

One game several times when I cast growth on a unit I got the visible effect of the shrink spell. Restarting the game fixed it.

I can still build drake and ophidians by double clicking the inactive button.

Sometimes when you kill an unclaimed hero their figure is left displayed on the map.

Sometimes when i am scrolling across the map with the mouse it zooms right out.

Trading items does not update the the current character when you exit. 

Events are happening out of order. ie 

1)I can be attacked by a monster and at the same time run out of its range and pick up an item, reveal a new area etc.  

2) I will pick up its treasure before the fight on the same square. (in one case i picked up the treasure and was offered to equip it during the fight when I opened the character detail screen)

3) It is possible to end up on the same square as a monster without a fight.

4) After killing a creature and ending up on its lair you do not always loot it forcing you to leave and come back.

Suggestion: Can we have a way of using books and healing items in the equipment screen instead of buying or trading them and then having to exit and find them on the character to use them.
