I've been playing about 150 hours now, give or take the beginning of constantly crashing about 50 hours ago, which caused me to start having to alt+tab out every 4 locations and restart the game through the mod manager. Here's the breakdown, and I really would love some theories: 1) I've done almost everything in the game: I have only the endings to do, except for the Lonesome Road DLC. I've visited almost everywhere, and the only quests left are faction-based quests where I have to take out Caesar's forts or something and wait to do so so I can do Caesar's ending. 2) Attached is a list of my mods. I have used them effectively for a long time, and only recently have attempted to do Bounties II even though it has been installed since almost the beginning. As I got through it further it caused me to crash as soon as I left a building after having completed my 3rd bounty. I got far enough that characters called Jack and Wendy showed up in Novac and randomly attacked me and they were killed before crashing, so I attempted removing it with no luck 3) I have tried disabling every single mod and I still crash within about 30 seconds. I have tried fast traveling and that crashes me instantaneously as well. 4) System Specs: GeForce 660ti 3 GB, Windows 7 on 3570 i3 Quad processor, liquid cooling and SSD hard drive plus 8gigs of ram (32 bit though, so only about 3.5 in use). I have used this all successfully for over 100 hours, this problem is not hardware related, or if it is, something completely illogical at this point. 5) Mod order. I have tried moving them around to no avail, but if anyone notices anything that could cause issue, let me know. I have attempted moving the Mission Mojave and the patch for repopulated wasteland ahead of NSkies and the actual repopulated wasteland, but that does nothing. Anyone have any thoughts or need additional information to troubleshoot?
