Implemented StringID ALREADY_INVIS

[demonstar55]

Well, a little nuisance I decided to give a crack at fixing. Basically before if you were invisible and someone tried to invis you again, it would cause you to become uninvised

did not test IVA or IVU but the logic is the same, so if there is a problem, it's not my fault!

only "problem" I've come across is bard song invis spams you if you're already invis (singing just the song w/o another invis on causes no problems)

You can stack Uinvis and Invis on Live... but you need to be using one of the group forms of the spells. They nerfed using single target casts. Invis overwrites Uinvis and vice versa.

So if I wanted to get both Uinvis and Invis, I would cast my Group version of the spell first, then the other person casts the group or single target version of the other spell. This is the common method used for collecting the crystallos base in Hills of Shade (where there's both undead and regular mobs that see through (u)invis).

This shouldn't prevent you from having invis, ivu and iva at the same time if that's what you are saying
