I still seem to be having some lag spikes, but it hasn't been too bad.
I did end up with a very strange happening with my tamed dilo. I went into the water while trying to fight off a raptor, and he ended up falling in the water, then swimming to shore and got stuck right there on the shore line. I punched him over a few feet, but could not get him to follow. I ended up borrowing a flyer from base to bring him home, but he still just stood there. Maybe logging off fixed it, so I guess I'll see tonight.
There was also someone online in a "Hunters" tribe or something like that, but the Dinosmatter base seemed pretty empty while I was on (although significant improvements are sure happening when I'm offline).
