This plugin modifies something permanently in your L4D2, even after I removed this plugin, there are still some bugs which started appearing after I installed this plugin.
If a bot dies, it sometimes randomly disappears completely, as if it's kicked from the server. And it also happens when someone disconnects. Instead of it switching to a bot, the bot just disappears, making me have to use sb_add every time someone joins or leaves, causing the bot to have 100 HP and dual pistols.
