Sorceress bugs

GAMEPLAY BUGS

1. Ice nova does not propagate on frostbolt correctly. (Before it was significantly easier to propagate it just having a cursor away from your character would work, in general direction of frostbolt, now you have to aim directly at the frostbolt to do it)
2. Savannah map can sometimes generate with part of it entirely cut off and unreachable with monsters unreachable on the other side, meaning map can not be completed, ever.
3. When you sometimes cast comet trough the doorway; depending on your positioning and i am guessing your character "sees" or "doesn't" see the other side the comet casts but no projectiles come falling and mana costs are still taken from you. Please make it so that you can cast where i can see, otherwise...well why can i see it then??? This is most prominent on Vaal Factory map.
