That means something is wrong with the settlement - to put it generally - and there's no real way to check what the problem is directly. Your best idea is to look at what you've changed and backtrack. You mentioned BI buildings - their models could cause problems if you haven't coded some of it right.
Well, on the left, I click on Advanced Options. Then I open the pull down menu for the Settlement level, I click on something, and it CTD's. The only things I changed while modding yesterday were the EDU, DMB, EDB, and changed the culture of a faction (although it has been reverted back to it's original culture.) And I've coded the BI buildings right, I just redid the tutorial and it still CTD's.
