I've noticed that the doors don't always open on the E1M5 donut (aka the dying part of the level). Has anyone else experienced this? I'm wondering if it involves clipping through the walls around the linedef that triggers the doors (edit: does not appear that this is the cause after reviewing the footage). If this could be pulled off with regularity it would be a huge game changer. At first I thought it was a desync problem, but now I see that the demo works in both cndoom and prboom-plus and does not trigger the doors.
