Greetings.
Upon stationing a small force (my sovereign, champion Janusk, and a small Militia team) the footsteps sound ended up looping. Again and again and again. It cleared once I removed the army from the city, but persisted until then. I am not sure which of the three were the cause.
The footsteps continue when engaging another army as well - so far, it's only been against animals/monsters and it loops until the start of combat.
Cheers,
