Which (of course) has nothing to do with this plugin. I am running both and have no problems with this plugin and of course any plugin limits it use to only servers that have it installed , whether its a free or paid plugin.
looking forward to the update and hope you have a Merry Christmas
Many plugins have API which allows other plugins to use those API or hooks and you do not have to have that plugin installed it just allows you to use functions from it.
Usually it's going to work better or make more sense having both plugins but it's not required.
MANY developers were blindsided as they were using API from BotSpawn to run the AI in their plugins. This is likely what Bazz3l is referring to.
Those developers have all been forced to write their own AI which is fine but this is no easy task and was really nice for people to be able to share the API from another plugin so that the AI was good to go and they just had to focus on the other functions of their plugin.
