I got my elevator to work, but the functrain (the platform) doesn't stop when it reaches it's spawnpoint (first floor where it started). again however, this only happens on the bottom floor, once it gets to the second, third, etc it stops and waits for the button to be pushed. how to solve this problem? i made sure in the functracktrain properties (the platform) the first stop target was path_track_1. ....at least that's what the tutorial said.
