buffs dont stack and cant see npcs?
 

some buffs dont stack unable to see npcs in most zones though I can see stuff like coldwinds in plane of tactcs which are invis mobs.
This is on test dev server btw. any help plese =)

You could start by sayig which server it happens on. Have you tried others? That would help figure out whether its a server specific problem, a server software problem or a client problem.

I've noticed the same happening on my server.

I tend to #cast raid buffs on myself to check max HP and the like, and I have to cast Bo9, Fo7, Symbol and BSS in a certain order, or they overwrite each other.

I also see the "invis" mobs (usually traps, flavour text, or some timer/ph for something else)

Using the default DB, sourced Myra's.
