[NEED HELP] TDM cars have disapered!

So I installed TDM cars a week or so ago and this morning I made a workshop.LUA folder that would allow players download the addons they needed for my server, since I restarted the server this time all the TDM car packs have disappeared from my 'vehicles' tab in the 'Q' menu. I am not sure why this has happned, or how I could possibly fix this. I would appreciate any help, thanks.

did you install the tdm cars in to the server? in addons
