The game crashes if...

DEMONADA, reinstall the game and install patch 1.4, then install 1.5 on top of it. Version 1.6 is buggy. In versions 1.3-1.5, 2.1, and 3.0, the game never crashed for me, neither when entering a garrison nor a Haven, and generally when entering any location. However, while completing all the campaigns of the original game and both expansions, I only entered a Haven 2-3 times. And that was only with a secondary hero.
