So a few discoveries puzzle me when trying to figure out how these effects are broken. I have looked into the EQMac on PC to see how the Titanium Client reads the spell files. When Titanium reads the spellsnew.eff and spellsnew.edd files.. the results are not correct in game. Many animations are missing. Which leads me to believe that the codes have either changed or they have been removed from the client entirely.
One thing that does work is the spell animation direction out of the hands. They do come out of the hands properly. So I also tested deleting the spellsnew.eff and spellsnew.edd files to see if that would restore the older effects. It actually worked 100%. Everything was restored like it was during the classic era. I know on this server, deleting the spellsnew files doesn't restore the effects out of the hands, but all other classic particles seem correct.
This leads me to believe that the direction issue with the new particles and the missing classic particles out of the hands is linked somehow. I know that when I start to go LD, spell particles from the hands stop working. There has to be some kind of communication required for the game to know where to put those particle effects on you and especially other people in your view.
Here are screenshots of the classic particles working:
