Doomsday Engine

On the episode 3 intermission screen in Ultimate Doom, there are several bloodsplats (indicating that a level is finished) and "You are here" arrows missing on the intermission screen. This can be noticed off the bat upon completing E3M1 and E3M2, in which that you won't see a bloodsplat appear on the E3M1 building. This is the full list that I compiled.

-No blood splat on E3M1 building (lowest building on screen)
-No "you are here" arrow on E3M4 building (skull building on east part of map)
-No "you are here" arrow on E3M6 building (top right building on the intermission screen)
-No blood splat on E3M6
-No "you are here" arrow on E3M9 building (skull head on bottom right of map)
-No blood splat on E3M9
