need help refreshing unit paths

[dizzt]

hi people, i have a map where units continuously spawn in the map and then die after a while, after some time the newly spawn ed units freeze up. i think the unit paths are getting too crowded. is there a way around this? or a way to refresh the unit paths?

If there are a lot of units for the same player, the movement may mess up. Try to divide the units for different players.
