The instance 'instances/gameplay/cube_dropper_multiple_normal.vmf' messes up my other instance in my map, the elevator instance messes up, it goes down instead of up, and I see a trigger block in it. And to top that all off, the cube dropper instance won't show. Help?

Whatever problems you're having probably have no relation to the cube_dropper_multiple_normal instance. Could you be more detailed? Simply putting an instance in a map shouldn't be able to reverse the direction of your elevator.

After I took the cube instance out, it went back to normal, so I am pretty sure that is the problem.
