Since yesterday i suddenly can't kill any dragons anymore they started to fly very glitchy and backwards.
It's very annoying and keep me from making progress in the game. (it's the ps3 version)

It's impossible to hit the dragons and no matter what i do the dragons keep moving away like it's pushed by an invincible wall.

My character is level 30 now and i don't want to start over.reloading the earea (fast travel) doesn't fix this.

what should i do ?

Wait until the 1.3 patch, I believe it will be before friday this week for consoles. My xbox 360 game is difficult to play on master with no magic/elemental resist, haven't had any backwards dragons though.

My dragons are going backwards too. I am on Xbox so yea just wait it out man..
