[WWSandMan]

just rename normandy folder as "-normandy" .... game will load default one and you'll be fine

( its because different load.ini on server and on your comp)

cheers

Ran into this issue myself tonight, and eventually worked out that very solution. Interesting to note that if you have vpmedia's (excellent) map textures mod (The link is inoperative) installed, and the server doesn't, you can't join that server. And vice-versa ... if you have that mod installed and other players wishing to join your server haven't got it, those players are ... left out. Not to say "screwed", but it amounts to the same thing.

/edit/

One more thing though... I got load errors on all the Normandy maps while trying to open them in FMB, as well as online. Renaming the folder (removing vpmedia's texture update mod for the Normandy maps) also allowed the Normandy maps to be opened with FMB. Odd.
