I don't see why/how they can't/don't get the entire staff(or 200 staff/players) to try these new features for a day because that would show up most of these bugs early doors.
Because they can't.
I think Jagex should have postponed this update until next week, so QA could have removed the bugs.
The 3K limit is very unnessacary. As has been said before, a 100-500K limit would serve the same purpose.
