the problem is in your server.cfg file ...if you have it execing the maps as TDM maps then it trys to do TOW as TDM and locks up

in your server.cfg file there is a line called sv_gametype

now if its 2 it will run all maps as TDM no mater what the map is (TOWorOBJ) 2 ways you can fix it

1 turn your vote option on ..when you vote it changes the sv_maptype setting and you can play tow as tow and obj as obj and tdm as tdm ..

2 change the sv_maptype in the server.cfg to "other" (if my memory is corect its 1 for ffa..2 for tdm..3 for obj..4 for other )

that should take care of your problem

(or just get hammers goodies map fixes and use the Conhammers mapfixes files to manage your map type ..)
