#define ROOM_VNUM_TEMPLE 7078 /* Green Dragon Inn - Main continent recall point */
#define ROOM_VNUM_ALTAR 7018 /* Bywater Temple - Where one goes to die */
Those 2 lines are the only relevent definitions. Vnum 7018 is not hardcoded anywhere I can find. The fact that you found them in mud.h suggests you're using an older version of the code. These definitions are now in olc.h and have been for awhile.
About all I could suggest is to try this from your src directory:
grep 7018 *.c *.h
then fix it wherever it shows up. You'll need to make clean, since you changed an H file too btw, in case you haven't tried that yet.
