To get the mod working more efficiently, You may need to install the mod manually by putting it to a 'custom' folder.
Go to SteamApps\workshop\content\362890\1371548782 and then move whatever is in the folder named '1371548782' to your bms\custom folder. If you don't have a folder named custom then make one in the bms folder.
If this does not work then its on the mods end. Hope this helps.

it doesnt look good on the headcrab zombie :/
