3 phantom enemies in Hell to Pay

[StarSpun5000]

So I was just playing through the 90's WAD Hell to Pay with ZDoom and I encountered this bizarre glitch(?) When I got to the end of Map28 I noticed that I had missed three enemies out of 99, so I decided to use IDDT to find them, but no matter how hard I looked, those three enemies simply weren't there. I decided to count the monsters in an editor when I noticed something strange, the editor had told me there were 96 total enemies tagged with UV. I checked in DSDA-Doom and found that the kill count there was correct, 93 (There were three lost souls which don't count in DSDA but do count in ZDoom, so the total is 96)

So this begs the question, why does ZDoom seem to add three nonexistent monsters in the level? Is this actually a glitch, or am I just missing something?

Did arch-viles resurrect any enemies, or pain elementals spawn lost souls?

 

That map does have three lost souls placed out of bounds, but GZDoom automatically removes them (not sure whether you're using ZDoom or GZDoom...).

In vanilla Doom, lost souls don't normally count -- they lack the MF_COUNTKILL flag.

 

It seems ZDoom gives them that flag, e.g. the DECORATE for the lost soul uses Monster which is a flag combo which automatically gives it +COUNTKILL, but there is nothing taking it away.

 

I'm guessing this is a deliberate decision, a change which happened long ago and they couldn't fix it because they needed to stay backwards compatible with stuff made for ZDoom.
