I thought the command for BP plugin is "/select area" (with a space). While the one for AP is "/selectarea" (no space). Shouldn't the only plugin responding be the BP plugin?
the command /select or /selectarea or /select area is used by more than one script, portals is another one too, IDK what command he used to bring up the selection tool, but what i do know is the command /delete con will output a message in chat if the BP plugin is installed, if no massage then i guess something has gone wrong or the script has not even been installed.
