Hmm, well I was able to play for most of today without incident, so I thought perhaps this was fixed in last night's maintenance. I can confirm this is not the case however, as it finally just happened to me again now while on a chocobo porter. Previously I was getting the error rather frequently, so I don't know if it is just random or really what is going on here. Either way it is remarkably annoying and hopefully we can get this fixed sooner rather than later.
