Some varieties are super sensitive to light pollution during the dark period, others not so much.
The worst sounds like the part when you brought them inside a few nights.
I have outdoor plants that get some light pollution from inside lights coming through the windows, but nothing too much. Never had a reveg or hermaphrodite problem with them.
Again, from the pictures I can’t tell if it revegged or if it’s just genetics.
1- what to do now? I would inspect for bud rot, cut away any you find, and monitor the plant to the finish. A first indicator that a plant is finished is that the pistols turn brown/red and start to recede into the calyxes, the receding part means your buds are swollen. Second would be the color of the trichomes on the buds. They start out clear, then turn cloudy, then go amber. Amber means the THC is degrading. People wait to see Amber because once you see some Amber, that should mean a majority is cloudy. Like a bell curve, a little clear, a lot cloudy, and a little amber.
2- What to do for next year? Try to place your plant/plants in full sun location, if you take inside cover with a box or bag.
If you are serious about growing a small indoor tent with a basic light would allow you to start plants inside for the veg cycle and move outside to flower. You could start a few, find a good female, then clone her and use the clones to go outside. Veg the plants indoors on 18/6 light cycle, them move out mid to late December to flower them(that’s the longest days so they won’t revert to veg). I say this technique because I find plants finish earlier this way and have less outdoor exposure to the elements.
There are a million techniques that will all yield good harvests, you just need to find the ones that work for you in your situation.
Any talk of going legal there? There is a guy named Heavydayze that has “a pot cast” show. He is an Aussie, super intelligent, and seems to be very active in the scene in Oz. He has a few clones he shares one is raspberry something, maybe mama. I suggest you listen to his pot cast and see if you can link into the community there.
Good luck, if you have any more questions let me know!
