On my last game I experienced two bugs:

1) After entering a Dungeon/Lair and winning the battle the game goes back to the world screen but the window with the loot and losses does not appear and I cant move units anymore (end turn still works, cities produce as normal, no units can be moved). I can even try to interact with the dungeon again but nothing happens. If I reload the savegame I made before the battle the same bug reappeared after each battle at a dungeon I tried.

2) In one battle an enemy unit was killed while moving due to backstabbing. The game froze with the sound of the unit moving continuing.
