I've had no errors, yet.. lol, but I've had some very bad lag in duties. Seems like not everyone is experiencing it either, as some were making jokes about dial up XD.. Definitely seems like a certain ISP or connection route is causing severe issues. Of the last few groups I had it seemed the people who said they didn't have a problem were all out of the US, although I'm not saying everyone within the US does have this problem (just that people confirming where they were from and not having issues were not connecting from within the US).

Had someone from east coast with the issue, and I'm from the west. So.. yeh.. Also just in a "did you normally have lag?" question- no, this is quite new and it's pretty bad (sometimes slideshow-y / rubberband like). Not a minor input delay.
