Yeah, ever since they took away cl_restrict_server_commands (permanently set it to one) a few months ago roughly, PTBx no longer works.
I posted it about it in another thread a while back (
http://forums.alliedmods.net/showthr...t=48450&page=5 ).
Technically, to make it work, whoever maintains it could just change it to use ma_swapteam from Mani, which works. Even though PTBx doesn't work right on my server, I still keep the plugin loaded (the team switch functionality off), because having it loaded makes it so ma_swapteam can swap living players without killing them. Sometimes to balance the teams, I'll do "ma_swapteam #ALL" at the end of a round, to switch both teams to opposite sides. Pretty neat feature, but far from PTBx's old glory.
