I live with a fellow player of the game, sat down to watch him play my scenario, aaand... Most of the triggers did not work. After some poking around I realised that I'd accidentally caused most of the triggers to revolve around a tree.
The errors have been fixed, and now each trigger should work! I apologise for the delay.
Ensure the king reaches the stronghold intact, enjoy the newbie triggers, and please leave a comment or review. c:
