I can acces all but the docks. And when Im through the door or in the neighborhood, it crashes. Im suspecting it's some sort of a conflict. Which mods besides better cities affects the area?

Before entering Anvil, open the console and write: TAI
Now try entering Anvil. If the game does not crash then it's a faulty AI Package, which seems to happen a lot in Anvil.

Didn't help, it still crashed. Will try two more times.

Edit: yep, still crashes. But atleast I got inside the light house.

Is it an instant crash? That could mean a faulty mesh.
You could also try TSCR from the console before entering Anvil to check if it's a script causing the CTD.
And posting your load order is always useful.

Actually, i think i know what triggered it. somewhat atleast. ′The newest OBSE. I went to anvil without it and with fewer mods running and managed to enter it. ^^ Thanks for helping

I'd vote for one of the "fewer mods running" rather than the latest OBSE on that one.
