I'm having a problem with the PS3 version of the game.

When i go to the companions they become hostile on me.

I think it has to do with dungeon quest evil in waiting: before this quest no problem
after this quest they get hostile when i go back to whiterun.

I this a bug? can i do something about this?

I can always go to a previous savegame but if i can fix this somehow...

Did you strike a companion too many times?

no they attack on sight, was going there to forge something and they just come after me and attack

Did you by any chance have a bounty in Whiterun? Companions are tagged as guards and will attack on sight if you are wanted with a high enough bounty.

Nope, no bounty, the regular guards do nothing.

just to make sure can i check somewhere if i have a bounty there?
