Having issues with interacting with NPCs in the game for either getting a quest, turning one in, speaking in dialogue, etc… and usually have to log out/log in for the game to work.
I don’t know if it’s the same problem as you, but i often have trouble interacting with quest givers too. I run back to give myself some distance to the npc and come back. Usually i can interact after I came back. If I stay near it when it breaks, it won’t fix itself without doing that.
I saw this with every quest stage yesterday in the max-level campaign quest chain. Pretty weird. By all appearances, I could have two different friendly NPCs targeted simultaneously: the quest turn-in/giver NPC I was just interacting with, and another friendly NPC that I had manually selected to try to break and reset my targeting of the first NPC.
Had to withdraw 10 yards to break selection and retarget to get the quest-giver to proceed.
I’ve done that also and it seems hit or miss being able to interact as needed.
