It seems some scrolls (item database) no longer link to their intended spells (spell database) but instead list Combat Effects: +1073741824 in place of the name and link. On the spells database, these same spells no longer have drop / vendor info listed.
Post on EQ Forum about this problem as well.
EDIT: Example: Spell: Burning Arrow doesn't link to Burning Arrow, versus Spell: Endure Fire does link to Endure Fire.
