I'm not sure what went on with this user but it startled me with what happened. So we all know that the winter/holiday update has a lot of issues and glitches, but I've never experienced this one before. So I buddied this user after we had a nice conversation and they asked if that would alright to buddy me. I had to then go because my medicine makes me very tired and it was kicking fast. Today when I logged in I checked my treasure hunts, inbox, and shops as usual. I then noticed this user was in my den, but when I went to my den all my furniture was bright red for a few seconds before turning to its normal color. I looked high and low and didn't see this user anywhere in my den. I left and went to do other things but it still said they were in my den. While I was trying to do these things I kept running into serious problems with my game, huge glitches, connection problems, not cuttin out in the middle of doing something to place me in a different part of the map, my character turning red for a few seconds. A mintue or two later they logged off and all the glitches and problems disappeared. I checked my buddy list and they had removed themself from my friends list, but I found it odd that all the issues were tied to them. I didn't have these problems with any of my other buddies, so I beleive this user is either a hacker or is carrying a virus. Just to make sure I changed all my login info to try and keep my account safe. Please be safe and ever cautious, and of course jam on.
