Sometimes when I want to talk to NPCs my game freezes and I can do nothing. All other animations and Players continue to move. So i have to relog each time my game froze. After that i can talk to the NPC. If i try to talk to a second NPC the hole game freezes again, and i have to relog....... and so on. Same Problem if i harvest Plants. :Question: :Question:
