[BAILOPAN]

In the next version of CS:S DM I will be removing native support for blocking rounds and removing objectives because you can now do it with this plugin: http://www.bailopan.net/stripper/

To do it now, simply install it and add this to global_filters.cfg:

filter:
{
"classname" "/.*bomb.*/"
}
{
"classname" "/.*hostage.*/"
}

That will strip all round objectives from your maps.

It is unknown if this plugin works in conjunction with Mani, but he's working on a SourceMM port soon I think.
