I think you should be able to sever waypoint connections simply by selecting a waypoint with a connection, holding Shift, & right-clicking the other waypoint you want cut. It's quite tedious having to completely delete the waypoint and restore its connections while also having to re-input its appropriate actions. I'm new to Bot waypoints, so I don't know exactly the distance from a 'point to another, like, say jumping and jetting, so I have to connect multiple 'points to one at times to be safe. Having to delete all those waypoints and restoring their proper positions (that especially is annoying >.<) & actions is tedious :-/
