I stumbled upon this error with my coop map , can anyone tell me how to fix this? (I googled it and it involves editing the polys using 3d programs which i currently don't have, i hope someone can help me with this)

first of all my english is bad... thank google translation...
hello community, I know this post is
old but it can help others.
I had the same problem with a navmesh map by PR in my mod. the problem was with the "ArmedCar"
I placed in the map a file "changearmedcar.con" and in it I placed "aiSettings.setVehicleClusterMapping ArmedCar Tank"
and it works perfectly
don't forget to activate this file in the init.con of the map
