Hope someone can help me here or point me in the right direction.

Im renting a remote dedicated server and running this amazing mod on it and have maybe half a dozen regular users and as many casuals,i use filezilla ftp to keep thing going but im having problems finding the right files to transefer to the server from my game when it comes to updating the server with the latest mod updates

Currently all i can do is transfer the whole file over well the second listing in the file and thats a 6.5 gig d/l every time i do it and pretty sure the updates arnt that much...Does anyone else do this ? or have a easier way for a relatively noob server admin to update the mod on the server?

At the moment the official update is good but i cant find the drums or railings so think maybe ive missed a mod update thats blocking them but i havnt seen this sort of thing b4 if ive been a bit slow updating the server with the mod update

Any help or info would be greatly appreatiated as i love this mod as do the ppl whpo play on my server
