In my map I have an elevator (func_train) triggered by a button, and I experience a very strange problem. When the elevator is first triggered, it works fine, but then about half-way through its path the brush stops moving, but I keep going up as if the brush were still there, but the elevator brush is below me stopped, and I'm moving up on the same path as I set the elevator to move but on no elevator brush, it looks like nothing is moving me up. My elevator is very tall (going from almost the bottom of the grid to the top), and I'm wondering if that is the source of the problem...Any feedback will be appreciated, thanks.
