5.1 Server crash on map change
Windows servers can not currently run hdn_origin, hdn_decay or any other map that is compiled with HDR. Remove these maps from the maplist.txt and mapcycle.txt files in the /hidden folder.
5.2 Client disconnect on spawn
If your server disconnects clients during spawn with the error: "material mismatch, we reckon you're cheating!", it means that the the /hidden/materials folder on the server does not match with the clients. This usually happens when you forget to install the server fix last during the installation process, but can also indicate that the files are corrupted or missing, which may happen during a transfer. First try installing the B4b server fix (5 MB). If this does not work, reinstall the materials folder from the Beta 4b Dedicated Server package (220 MB).
5.3 Bans reset on server start up
The commands writeid and writeip store bans to the banned_user.cfg and banned_ip.cfg files respectively. These commands must be executed after issuing a banid or banip command for the ban to be saved. Furthermore, the ban lists are not automatically loaded when the server starts. You must tell the server to load these in your server.cfg or autoexec.cfg as follows.
Example server.cfg settings:
Another common mistake people make is including a writeid and/or writeip command in their server.cfg or autoexec.cfg. If this is done before the files are loaded, the file will be overwritten with nothing. There is no reason to have either of these commands in your configurations, as they only need to be executed after a new ban is added. Either remove them or make sure the lists are loaded first.// Ban settings
exec banned_user.cfg // Load banned STEAMs
exec banned_ip.cfg // Load banned IPs
5.4 Maps repeating
Sometimes a server will get stuck playing the same map over and over. This is usually the result of a missing or misspelled map in your mapcycle.txt file. Also, linux servers are case sensitive, so make sure you check that since some custom maps have capitals (Hdn_Ravenholm, hdn_SeaMadness, Hdn_storage).
5.5 Headless players
Hidden is designed for 9 players but the server supports 10 slots so servers can keep an open reserve slot. If you run your server with 10 slots, make sure you have at least 1 slot reserved to prevent the head bug or use my headbug script to fix this.
5.6 Sonic alarms don't work & round restart exploit
Your server needs to be patched. Install the B4b server fix (5 MB).
