ZDoom

It's the same. You can copy it without doing any damage.

I notice that the only file changed for this fix was thingdef_parse.cpp. Can I just drop this into GZdoom for a personal build or is the GZdoom version different?

breakable NJHateTarget1000 //1000 hit points
   {
       DoomEdNum 11000
       Sprite TNT1
       Frames A
       DeathFrames "A"
       Radius 20
       Height 56
       Health 1000
       Mass 100
       DiesAway
   }
   
breakable NJHateTarget100 //100 hit points
   {
       DoomEdNum 10100
       Sprite TNT1
       Frames A
       DeathFrames "A"
       Radius 20
       Height 56
       Health 10
       Mass 100
       DiesAway
   }

Deprecated I know, but this is from a DECORATE file I made years ago (actually to work around a bug with hate targets at the time):

As a side issue, the reason that I posted a screenshot of the dialogue rather than a log file is because the logfile did not capture the error message but stopped at "LoadActors: Load actor definitions."
