So, I was playing a custum user map on the PC version. I got to a door and shot the button that was supposed to open it. The glitch was the door kept on moving upwards without actually opening the path. It felt like it had portals on both end of the door and it just went on forever. I loaded the map on other Duke3D platforms and it opened as it supposed to. I’ve also encountered this glitch with another user map but it was an elevator instead, the elevator just kept going forever.
If it helps, the door was timed; it will close again in 5 seconds and i would have to press the button to open it again.
