Everything was goin ok for awhile,level 35 now then all of a sudden i can't sell or buy from markets,vendors etc. The dialog shows "what have you got for sale" and when i choose that option their inventory or stock of supplies doesn't even show up on the side and i'm stuck standing in front of them.What can fix this problem if anyone has encountered this before.

And no...items aren't stolen and it happens with any seller on the game even the fence npc's also.

PS3 strikes again
restart the game and restart the console
go back to ealrier saves
other than that you could do an RP thing

Thank you,sad that i have to start all over but i did anyways and even the earlier saved games did the same thing.So new character and new build...lvl 23 tank build so far so good...for now. lol
