Would it be possible to improve the danger / attack warning in two distinct but crucial areas.
Attacks against walls / doors. At the current time you don’t get a warning when your walls / doors are being attacked. So it prevents the early warning and extra preparation they are meant to provide.
Attacks / Potential Attacks on Hearthlings - at the moment the warning you get that a hearthling is under attack is so late in the day you have no chance to remedy the situation. The warning of imminent attack should be much earlier to permit you a chance to react and avoid the incoming attack.
