I have a similar issue to of the post above.I have Step:Extended installed and it's stable.I downloaded the Explorerers pack and followed the directions (according to Step:Extended)Basically, everytime I enter certain cities (Riften, Windhelm, etc..) It CTD's. It CTD's when I enter dungeons and some houses too.Also sometimes I noticed some farmhouses and buldings will have multiple textures loading at once.Sometimes when I'm running up to a city, or establishment, The whole city will flash into white, and CTD.I've tried two days worth of conflict resolution. These problems won't go away. I might need to just get rid of the Explorers pack if I can't get some help.Anybody have any ideas what's going on?
