Fast download only working before first map change

[Ziks]

I've recently set up a TTT server (this is the third GMod server I've helped set up). The server has about 10 custom materials (materials that came with the Evolve plugin and a couple of custom TTT weapons). I've also set up a download server for the server, using this config:

sv_allowdownload "0"
sv_allowupload "0"
sv_downloadurl "http://[host name].co.uk/download/garrysmod/"

I have all the materials from Evolve and the custom weapons in their respective folders in /download/garrysmod/materials/, and all our maps compressed to .bz2 in /download/garrysmod/maps/.

When I join the server right after it has restarted, so before a map change, I correctly download all the materials and map from the download server (after deleting them locally). I can see the materials in-game fine. However, after a map change, I can no longer see the materials (not the purple checkerboard, just blank space) and I get spammed missing material errors. If I join the server after at least one map change, the materials appear as purple checkerboards.

The materials are not re-downloaded after the first time, so I think I have everything set up correctly in the download server. I have double checked the paths to all the materials, and they are all the correct case etc.

The odd thing is how it works on the first map after a server restart, but not after that.

Does anyone recognise this problem? And has anyone successfully hosted a server with a download server and the Evolve plugin, with materials downloading correctly?

This is the biggest /facepalm of the century....

sv_allowdownload "0"
sv_allowupload "0"

.....really? What does 0 mean? It means nothing, null, nada. In a boolean it means false. In Binary it means off. Really? Come-on..... Change then to 1 -.-

sv_allowdownload seems to only have an effect when there is no value given to sv_downloadurl. I have tried both 1 and 0 anyway. Please at least know what you are talking about before you make a comment like that.

I take it no one has had this before, yet I've had it on every server I have hosted

I can't be the only person to ever have this, we've had it on three different hosts, one of which provided an automated download server system.
