Playing on another official testlive server I noticed these things:
My character got stuck at certain surfaces (edges where the “world texture” changes, sometimes at the end of ceiling pieces when I wanted to jump downwards in my building).
If this happens, I get teleported back a little like a rubber banding effect.
Humanoid NPCs are fast as hell. All attack animations, even simple walking, seems to me like 1 1/2 times as fast as before. I was riding a horse and a certain npc continuously followed me even while sprinting.
Thirst is very intense, even with the soothing effect.
