Invincibility bug in Dr Rushmoor's castle

[tygara]

This is a rather big bug in my opinion, so really needs to be fixed before coming to the life

The moment ya pick up a invincibility buff, the description says that you arent suppose to be able to cast spells.
Well, once ya recieve that buff, ya actually are still able to cast spells, but something else happens. Once ya consume a mana potion, you do NOT recieve the amount of spellpoints from the potion, but the potion is lost
Look into this before bringing it to the life server please, this is in my opinion a serious buf that just cannot come on the life.
