I was on my main character working on the new MSQ 4.5 content that came out. When I encountered an error of it automatically logging me out and closing the client. At first I thought it could be on my end as I had just recently redownloaded the FFXIV Client after not playing for a while. I was able to log on all my other characters on the same account without any problems. I am on Cactuar which does tend to get very crowded during new patch days. Could this be the possible cause?
