Patch updated.

Part except the spell casting on invisibility aura removal in [11851], Thank you!

Would it work on One as it is? Or would need extra modifications?

should be identical in backported I think.

Confirmed.Just tested, works like a charm in One also.

Btw why wasn't the aura removal part included?

It didn't feel good

I don't know the general spell casting code too well, hence I cannot exclude that there are better ways to do what must be done. Hence I hesitate.
