Why is ADD_SPELL overwriting?

[subtledoctor]

I want to 1) change the IDS entry for the existing Identify spell; and 2) add my new version.  Here is the basic code:

COPY_EXISTING ~spell.ids~ ~override~
	REPLACE_TEXTUALLY ~WIZARD_IDENTIFY~ ~D5_IDENTIFY_OLD~

ADD_SPELL ~%MOD_FOLDER%/data/d5tb110.spl~ 2 1 ~WIZARD_IDENTIFY~

What ends up happening in SPELL.IDS is this:

2110 D5_IDENTIFY_OLD
2110 WIZARD_IDENTIFY

I expect my new spell to have a distinct RES.  What am I missing?

Maybe something special about vanilla IDS names?  This workaround seems to work:

COPY_EXISTING ~spell.ids~ ~override~
	REPLACE_TEXTUALLY ~WIZARD_IDENTIFY~ ~D5_WIZARD_IDENTIFY_OLD~

ADD_SPELL ~%MOD_FOLDER%/data/d5tb110.spl~ 2 1 ~D5_NEW_IDENTIFY~

COPY_EXISTING ~spell.ids~ ~override~
	REPLACE_TEXTUALLY ~D5_NEW_IDENTIFY~ ~WIZARD_IDENTIFY~

Did you try CLEAR_IDS_MAP after updating spell.ids? It is possible that ADD_SPELL works on a cached ids map otherwise.

Many years ago, I faced the same issue on classic games with missiles and projectiles ids files. As @argent77suggested, a CLEAR_IDS_MAP did the trick.
