Ok, so I've had some lagging issues and a similar CTD issue in the past, but my past issue resolved itself.

-- At the beginning of "Take It Back", I leave the Bailey and run under the rising gate. (For the record, I'm running FWE with increased spawns; Other than slight lag, it doesn't seem to cause any issues) I follow LP and my BOS comrades and before I can make it to the edge of the bridge *bam*, CTD. It seems like it freezes in exactly the same spot, because loading the same save and just sitting and watching, there aren't any issues. I'm afraid it's some kind of a script issue that is causing a CTD, but am unsure. How should I go about getting past this issue, or checking it to prevent it from happening elsewhere?

Thanks guys!
