SPLPROT targeting of EA now works?

[temnix]

I remember distinctly that trying to make a spell hit only PC, or ENEMY, or NEUTRAL with effect 326 never used to work. Effect 177 had to be used. It was some kind of bug, apparently. I don't know if 326 works now, strictly speaking, but EA-aimed protections with 318 do. I'm blocking everyone but PCs with the "Allegiance !=" line here. Has something been fixed along the way that I don't know of? By "now" I mean version BGEE 2.5, which is what I have.
