I. This is a pretty easy bug to run across so i apologize if i am repeating something that is known already:
When inside the tactical map screen:
1. Select own unit.
2. Give command to move to adjacent tile.
3. As the unit begins move animation, immediately press Space Bar (Pass Turn).
4. Enjoy
This isn't a solid crash, but you cannot progress any further, as the end turn button doesn't work, you cannot give any further commands. Auto-Resove does work, I just use that to end the battle and reload the last save.
II. Also, as a side note, it would be nice to introduce more error messages. I spent a few minutes trying to cast a spell a spell on my own town, without effect. I would select my character, select the spell, the cursor would turn green as it hovered over my town, but nothing happened. A few frustrating minutes later I managed to cast the spell, but only after i had gone mad and smashed keys and commands. It could have been a bug, but it could also have not been a bug. Maybe by moving my character, I had reset his action points, and that is why the spell was cast finally. Maybe I did not have enough action points on the strategy screen to cast? If so, it would be really helpful to have error messages so the player knows he is forgetting something.
III. Auto explore is still buggy (unless i am overlooking something again), as it will not turn on sometimes.
