Hello, and here's my two cents worth of knowledge... I to am (was) having this issue and after several hours of reading and searching for a solution I have finally found one. I had recently read that the Rayeks End and Riversde Lodge mods, while they have been made to be compatible with each other, they are not compatible with each other during certain parts of the game i.e. "send a detachment to riverwood at once" and then CTD. After disabling one and then the other and then both at the same time, I was still getting the CTD. I have been disabling my mods in groups of 3-5 at a time for the better part of the day now and to make a really long trouble-shooting story short... If you are using the following mods: Grillis Home Riverwood; Better Villages; and Rayeks End + RiversideLodge, disable these and then reenable after the "send a detachment to riverwood at once" speech. Don't forget to remove anything that you might have in the homes. I myself may just leave these disabled from here on out, though they are among my favorites. And even though I do not know ripple, please read his/her post becasue it's full of sound advice and I am of a like mind when people don't RTFM! Thank you for reading this and luck to you!
