Trying to get BotChat to work on my Vampire Slayer server. No luck yet, even when the probability for chat is set to 100%. Utterly silent bots running around killing eachother

What could be wrong?

Excerpt from my bot.cfg

min_bots 4
max_bots 6
bot_chat_percent 100
bot_taunt_percent 100
bot_whine_percent 100
bot_chat_tag_percent 20
bot_chat_drop_percent 20
bot_chat_swap_percent 20
bot_chat_lower_percent 20
bot_logo_percent 40
bot_reaction_time 2
#random_color 1
#botdontshoot 1
bot_strafe_percent 10
#addbot
#addbot
#addbot
#bot_strafe_percent 20
#addbot
#addbot
#addbot

Is something missing?

Thanks in advance / JGD
