couple things I've noticed in CC:
While a mob, coming into the immediate area, and even if still offscreen, is trying to lock on, frozen for a short time
When a new 'sound' starts to play, frozen for a short (my singing ball does this, every time)
Coming near massive house contents, such as in Luna - and not just inside the walls either - you'd think being completely outside the city walls this wouldn't happen
There's a spot in SA; at the west end of the long hallway adjacent the area where wolf spiders are, just before it turns S. and goes into the large room w/ goblins. Sometimes I get over a 10 second freeze here (enough to think I lost my IP). Happens once every time I go.
yes, queen's castlein ter mur, laggy as crap! I bookmarked the forge, and just don't use the rest, just a wasted area
