For some reason, some events that are super important are easy to miss. Can't remember all the ones that were bothering me off the top of my head, but strange moods and migrants arriving have huge potential fallout, and basically just pop up as an Icon on the left side of the screen. Figured out how to to make them show a warning box. I'm sure there's others I'll add as I play.
Goto: [your whatever]....Steam\steamapps\common\Dwarf Fortress\data\init
Then go to the strange mood one and add :BOX so it becomes:
Code:
[STRANGE_MOOD:A_D:D_D:BOX]
Now there's a popup and the game pauses when a strange mood happens.
