I want to try to make my 4 turns per year script trigger when you click on a settlement, character or the end turn button.

I have a couple questions: is there any long term negative effect of having the trigger in there? It will check every time you click that button to see if the script is running, right? Are there any known bad effects of that?

Second, I can't find the darned thing! I've found triggers for clicking on characters and settlements, but not the end turn or next turn or whatever you call it button. Anyone know where that sucker is?

Thanks!
