I talked to each NPC at the Darkmoon Faire, played with the remote-control tanks, and chased around the frog-selling goblin for 10 minutes. It has hard because right when I had caught up with him, the screen turned black for several seconds because the graphics driver failed, and he got away. Then I went to Westfall via hearthstone and delivered a message to Gwyrn Stottlemeyer, who sent me to Stormwind. I rode a gryphon and jumped into the lake, where I accidentally dove underwater by left+right clicking, and I didn't know how to resurface, so I drowned.
Now it's logged me out of the server and I can't log back in.
Edit: Now I can log in, but weird things happen like NPCs are missing, or I can't talk to them
Edit: I handed Gwyrn Stottlemeyer his letter from the head of the Stormwind military, but he didn't say anything at all. I looked around, and weird things were happening, like gryphons hovering in the air, flapping their wings, but going nowhere. I walked back up to the head of the Westfall People's Military, and everything moved around REALLY fast, then I was logged out of the server. I talked to him again when I was logged back in and got another quest involving capturing a Defias Messenger, but I missed my congratulations message.
It's really, really hard to feel "into" it at all on days when things like these keep happening. I logged out and I am not playing for the rest of the day. One or two days left on my free trial. Next time I make another account so I can get another free trial, I'm going to make it an undead mage and roll on a high population role-playing server, so I can find a group more easily.
