Great next step for the game, no crashes so far!

1. When Autoturn is enabled and the last action of a turn gives a hero enough XP to level up the level up screen will be shown, but the AI will already take its turn (or at least the player's units that received orders for several turns will move - not sure about this). This makes it hard to follow the gameplay and level up should freeze the gameplay until the screen is gone.

2. After researching my 1st or 2nd tech the game didn't continue to research and it took me many turns to figure out that it said "No Research". I don't know if the player can choose no research, but this shouldn't happen and the player should be forced to select a tech before the turn is allowed to end.
