Crashes whenever a map has a Sector Set Portal

[WMan22]

I tried to play a map I created in vanilla GZDoom VR and the moment a Sector Set Portal in GZDoomBuilder's feature set comes into view, it consistently crashes every single time. The map will load up, and it won't crash until you see the sector set portal itself. This has been a problem in a few mods I've tried to play that use map trickery to create non euclidean space.
