I was playing on the server ealier this morning (U.S. central/GMT-6+1) and something was way off... Either the server was not responding to clientside requests very well, or I was experiencing horrible lag. I would request certain commands and have to use alt + tab for the commands to be carried out. One example would be rest, "Alt + tab" to start and "alt + tab" to end, or I could have just wated for the process to end. (Don't know why I chose to use alt + tab twice for the rest command.) :|
Yesterday, I, and someone else noticed that sometimes other player bodies end up with missing parts, like the torso. :/ Another one of the times I played yesterday, my maps got reset.
