Hey everyone, I'm developing a mod for an area that requires a "buff" to enter and stay inside. This mod checks if the player has the buff; if not, they will be teleported to a location set in the config. The buff is also configured in the XML. Below are the codes, but I'm having trouble adjusting the part where it checks if the player has the buff. When I enter the area, it says I don't have the buff (even though I do), and I'm teleported to a location I didn't set in the config.
