Haven’t experienced that on a regular enough basis to say it’s anything other than very (EXTREMELY) infrequent and merely random technical problems that online games and servers have. The cross foundation and ceiling tile instance being the exception. There MAY be those true hackers that can, but I credit most of it to assumptions and misinformation. I have no idea either why these performance issues have come back, but your observations and mine didn’t quite line up. Every server is a different story I suppose.
I noticed this problem well before I finally tracked down their marketing gif for that patch and posted. Been a couple months since June and it just gets worse and more and more complaints hit the forums.
