I do n’t know why it is not highlighted because of distance。

When this happens? Always when in a group? Only on a mage? It started happening after an update?
Type /dump IsSpellInRange(GetSpellInfo(1459), "player")
Does it say 1?

not yet，
at first when lv 1-20 have this issues，lv60 not。
Always when in a group or party。 not just mage。
result
lv 60 without issues

lv 35 with issues

You pasted it wrong, remove spaces.

sorry ，
lv 35

Ok, now try /dump IsPlayerSpell(1459)

It seems the issue is that your 35 somehow doesn't have Arcane Intellect Rank 1 trained. I don't know how that is possible

lv 35

lv 60

yes，lv 35 Learn Nothing

now i Learn Arcane Intellect Rank 1，it is ok now
but when i lv1，how to show it

lv 35 just for item 12360 and item15846

Arcane Intellect Rank 1 is available from lvl 1 and costs 10c. Most people will never notice this as it stops being an issue 3 minutes into the game, but mages need 30yd range change instead of universal 40 for decursing and buffing and that is the best option

Thanks, I know the solution, Aptechka is very good

Now I think, if a player does not learn the spell , there have a note

Ok, i'll make it smart
