I have Oblivion Mod Manager, and run the game through OBSE and have Qarl's texture pack installed.

Ok, basically I started the game, it all runs fine, incredibly smoothly actually. However whenever I go to leave the sewers the game crashes and says there is an error. I assumed it was a problem with mods so I tried disabling various mods as a process of elimination, but it seemed none of them specifically were causing a problem as the game continued to crash whenever I exitted the sewers. To see there wasn't a problem with my computer I disabled all the mods and ran Oblivion normally (not through OBSE) started a new game and I could exit the sewers just fine. I did the same thing again running it through OBSE and again everything was smooth.
I made a saved game just outside the sewers and proceeded to turn the mods on one at a time and then loading the saved game just outside the sewers. The game loaded fine each time however, every time I tried to use the console to do anything the game crashed which is annoying because I use the console a lot for various things that aren't cheating
Anyway I turned all the mods back on and loaded the game just outside the sewers, no crashes, it ran smoothly. I loaded the same character just before the exitted the sewers and then exittted the sewers, the game crashed.
I'm not really sure what is going on. I could play the game with just one of these problems but not both, if I can make the console work then I can load games from outside the sewers and use cheats to edit my character, or if I can find out which mods are conflicting I can play the game without the console, although in all honesty I would really like to find out why using the console crashes Oblivion.

Does anyone know what could be making my game crash just as I exit the sewers? Or what is causing the console to crash the game? Any help would be appreciated.

Oh, PS: I can use the console inside the sewers, to get to the testinghall, I can then exit the testinghall into Hawkhaven but as soon as I map travel anywhere the game crashes.

Do you have the latest version of DR 6? I seem to recall something about transition crashes for that? (not completely sure though.....)

Also, you need to reverse the order on these two:

xu Patch for Ancient Yews and Arrius Creek.esp
xu Arrius Creek.esp

Thanks, I've reordered those two mods now. And I downloaded the latest version of Dead Reflex only a few days ago so it is definately up to date. I just wish there was some way of working out what is going on.

Ok, I have done a bit more testing and found that if I load a saved game just after I exit the sewers (and I've put all the mods back on) I can map travel anywhere I want without a problem. However if I map travel to inside a city and then I try to leave the city the game crashes. So I think it would be ok to asume one of the mods or a conflict of mods is making me have problem with transitions. I have tried this with dead reflex both on and off and it isn't DR that is causing the problems.

Also I'm not sure if this is related at all but I am running the game on HDR instead of bloom. If I try to change it to bloom in or out of game when I load it up again (so the changes take effect) the there are no words in the main menu, just the background video playing.
