Gmod 13 - dedicated server - TTT - game mode stays as sandbox

[Turbine]

I've been trying to get this game hosted for a great deal of time. Got quite a headache now and it's driving me insane.

My setup is the following

server.bat

srcds.exe -ip "192.168.20.5"
+hostname "Test"
+exec server.cfg
-rcon_password "does not work"
-port 27016
-maxplayers 16
-game garrysmodbeta
-gamemode "terrortown"
-console
+map ttt_island17
-autoupdate

server.cfg

ttt_preptime_seconds 30
ttt_firstpreptime 60
ttt_haste_minutes_per_death 0.5
ttt_round_limit 4
ttt_fretta_mapvoting 1
ttt_traitor_pct 0.25
ttt_traitor_max 4
ttt_detective_pct 0.15
ttt_detective_min_players 1
ttt_minimum_players 5
ttt_postround_dm 1
ttt_dyingshot 1
ttt_no_nade_throw_during_prep 0
ttt_karma_ratio 0.0020
ttt_karma_round_increment 0
ttt_karma_clean_bonus 0
ttt_karma_traitorkill_bonus 50
ttt_karma_low_amount 800
ttt_karma_low_ban 0
ttt_karma_persist 0
ttt_det_credits_starting 2
ttt_spec_prop_control 0
ttt_idle_limit 60
ttt_namechange_bantime 0
ttt_detective_hats 1
ttt_locational_voice 1
sv_lan 0
sv_region 6

But no matter how many times I tell it to load "terrortown", it just stays as sandbox.

I've also checked out the latest SVN release, but that didn't fix the issue either.
SVN: "https://facepunch.svn.beanstalkapp.com/garrysmod/v13/garrysmodbeta/gamemodes/terrortown/"

I have absolutely no idea what to do, I've been searching Google for hours to no working solution.

Please help, Turbine.

I have no idea.

If anybody has a working server, uploading would be nice. I'm going through various SVN versions of just the game mode, didn't make it work.

Also hosting through game crashes when someone joins.

change +sv_gamemode to -gamemode in your bat, and take out sv_defaultgamemode.

[Edit]
Thanks, changing -gamemode to +gamemode it now starts TTT. :) Although I have no idea what the difference between - and + are

I just have to figure out why it stops you connecting to any server (even locally) when hosting.

Commands that start with - can only be ran at startup and not changed without restarting. Commands without a sign or with + are normal commands that can be ran at startup and/or during the server being up.
