there is a 2 layer cliff on the way and i want an elevator to move units up so they can go on top of the cliff and continue on. the elevator works, it goes up when the unit steps on it, but then the unit cant get on the cliff even though they are the same hight... and i DID open the wall facing the dliff when it gets to the top. but its still not working, the unit cant get on the cliff... anyone know whats wrong? |
