Now every time I fast travel a horde of bandits apear and attack me
of completely random enemys

I try and try but no matter what I do I cant resurrect anything
New event
Ok resonantly I killed some people using my sneakyness
and then I got 3 hired thugs following me
Not killing me or attacking me but following me like a companion and helped me fight off 3 giants, 4 woolly mammoths, and even bandits
then they just turned on me
this is the 3rd time sense the update.
Your "New Event" is normal. The thugs won't attack you inside the city, but leave and they will proceed to "teach you a lesson." By that I mean get themselves FUS RO DAHed to Oblivion.
Your first "event" I've had happen to me as well. Fast Traveled and ended up with like 5 spiders (including Nimhe who I already killed a while ago), a couple of Falmer, some poor bandits, a couple of necromancers, a Draugr Scouge, a horse, and a dragon... but I think the dragon was just coincedence.
I think this issue has something to do with cell cleanup. Basically, a whole bunch of spawn points have reset at once. It's a one time annoyance when you enter a cell after patching and it will level out quickly.
This seems to be it. After wiping out my surprise and hostile traveling companions, I fast traveled again and didn't have the issue again... but the horse appeared again. Guess I'll have to kill him if I want him to stop following me.
Other than starting a new game, this seems to be the only way to "fix" the issue. I tried seeing if I could prevent it from happening, but nothing seemed to work. Fast traveling normally caused it. Where I fast traveled to didn't matter. Also fast traveling via the carrage causes it.
So, my only advice is kill them all and they'll go away.
