JNGP comes with an option to disable walk movement, fly movement, and building on certain terrains, you could use something like that as a "pathing blocker" which wont create extra lag from doodads

i thought the post about exploding computers and reality altering effects was quite funny...
i did not realize that doodads do not create lag, i thought they created issues with startup if you had too many :/
