No one can fix it.

This sucks, and the only response is silence

(Also note: the default behavior of the patch of making all blood other than gibbed blood black isn't a "patch done" condition either I'd say :/ )
I hate that I have no ability to help fix this. I don't even understand the blood code.
(I also tried with the patches effectinfo aswell)
Also another thing I found is that if I start a botmatch from the menu no bots come it. I have to restart the botmatch from the menu again to get bots to work. I'll try with vanilla svn now and see if it's a bug in svn.
