Can't cast positive spells on a target under Divine Shield

[Appled]

Greetings dear OwnerCore community.

In retail (not sure how this works on TC2 but if I remember right it works properly there) if you have Divine Shield on you, you are immune to negative spells and attacks but friendly targets and yourself can cast positive spells such as buffs and auras on you.
On Arcemu if you cast positive spells on you while under Divine Shield, the buff animation will be displayed on you BUT you won't get the actual buff. Same applies for auras. If you change your aura to another, you will lose the current and you won't get a new aura.
So basically you are somewhat immune to positive spells. I've been searching for two days now and I can't find where in the source is this determined.
Anyone has any idea relating to this issue?

This is a bug you should probably report to ArcEmu.

Hmm looks like I fixed it.
Shortly said in Unit.cpp AddAura void. It was checked if you are immune to spell schools but wasn't checked if the aura was positive or negative. Therefore I added a check to check; if the aura is not positive, then do not cast it.

Great, not submit the patch to arcemu so they benefit of your work aswell!
