Map 2 – it seems Linedef #731 does not have the DR action set, so it is possible to get locked inside the little closet with the shotgun and shell box near the start.
BTW, funnily, the fixed WAD now works for me in Boom, MBF and Crispy Doom, but PrBoom+ 2.5.1.4 throws an R_InitTextures: Missing patch 301 in texture SKY4.
I haven’t kept a copy of the first version so I don’t know if it happened there as well.
