I have one problem with Fallout 3 Alton IL mod 2.01.
I am using TTW 1.41a.
Game crashes always when going closer to the city of Old Geoffrey. Otherwise it seems to work nicely.
I did not have that problem when playing Fallout 3 vanilla. Game loads some distant meshes and textures and crashes immediately after that.
The mod developer said that Alton mod uses some meshes from Operation Anchorage at the Old Geoffrey when i asked if he had any idea what could be to cause.
