Yes Fortunes of War... in this instance it was 2nd turn first impulse my Vickers mg firing at range on the second story of the church was all it took to start the fire, very unfortunate for sure. Although it was very fun watching the building slowly burn around the defenders, when it came time to cap it was impossible. Perhaps a simple 'house rule' will suffice in the board version. Maybe an option in the digital version? a tick box with no burning buildings? or perhaps the rules could be refined a bit more.... say an important objective building has to be 'controlled' by either side with at least 1 squad to retain it, otherwise it goes neutral. or have whomever controls the most locations, controls the building for victory purposes. Just some ideas.
love the game system all in all. very fun!
