Has anyone played 2048 Unleashed?
I'm on Map 38, and the map just won't continue. Some walls that are supposed to raise never do. I looked at it in GZDoom Builder, and the walls have Tag 666, but killing boss monsters, or putting on this compatibility option and doing it, won't work.
Here's a video of the map working as it's supposed to:

I was playing on GZDoom 3.0.1 with Smooth Doom, but going back to the version used in the video, 2.0.05, and with no mods but the mapset on, it still didn't work. Is my version of the wad just defective or something?
Here's a link to the wad:
