if I were psychic... yes. I would know what would happen in the future.
I would say, a plant that's been flowering for 6 weeks (pretty far into flowering in my opinion) and has adjusted to the 12/12 lighting cycle, would really dislike being switched to 24/7 lighting for 12 days straight.
I'd say, the worst thing that would happen would be, that it may cause your plant to hermie on you (go male)... or at the very least it def. more than likely has stunned the plant.. therefore its in shock and has delayed flowering for a period of time as well. How long of a delay? I don't know the answer to that either bro.. but I would probably think, that whenever the plant recovers from being abused with lights.. it will then hopefully return to flowering. If not, then it will start spitting out balls (aka Pollen Sacks). And of course.. seeds.
Just hope for the best. Next time, I wouldn't leave ur plant with anyone.
One person knowing your growing is one too many.
but yeah, good look to ya. Your going to need it.
peace.
